Here is a type of article you
will not find in today's modeling magazines; it is an in-depth look at the state
of Russia's space program in the late 1960s. In 1968, the Cold War was in full swing,
and recently constructed survival shelters were still stocked with food, water,
clothing, and medicine in case some crazed general in Russia decided to push that
would launch a barrage of ICBMs over the North Pole and into the USA. President
Kennedy's challenge to send a man to the moon and safely return him was a year away
from reality, and the Space Race was revealing how different design and execution
strategies can be toward accomplishing the same goal of manned space flight. Maybe
it is cultural bias, but I have always believed that American rocket design looked
much more eloquent - even beautiful - than the Russian efforts. Could it be a result
in the vastly alternative mindsets of Capitalism versus Socialism/Communism, where
the former had as part of its nature a desire to appeal to consumers who had a choice
in what they buy as opposed to the latter where consumers had to accept what the
ruling class offered. Functionality was the only requirement. Communism produced
ugly, black cars while Capitalism was offering vast choices of colors and styles.
Members of the oligarchy imported their cars. The Worker's Paradise thing never
did fool the proletariat. This article from the July 1968 edition of American Aircraft
modeler is an excellent illustration of what I mean.

at that date was impressive.

EXCEPT for the obvious, well-documented results of the Soviet Union's space program
in the past decade, there has been a shroud of secrecy around the actual vehicles,
techniques, and equipment used by the Soviets to accomplish the numerous "firsts"
in astronautics. Tass, the So vie news agency has never been reticent about announcing
every Soviet space achievement as it has occurred, and Sovfoto has released numerous
pictures of the Sputniks, Kosmos, Luniks. and other satellites and space probes.
As a result of this secrecy, a tremendous amount of speculation about the Soviet
space program has been carried out in Europe and the United States. Some Soviet
space watchers, myself included, have continued to keep a quiet archive, awaiting
the day when enough information became available to piece together a logical, unemotional,
solidly based historical story of the Soviet space program.
In 1967, the year of the 50th Anniversary of the October Revolution and the 10th
Anniversary of the launching of Sputnik I, this shroud of secrecy was lifted by
the Soviets. As of this writing, the shroud is almost completely gone, allowing
us to determine exactly how the Soviets did it.
So much data is now being released so rapidly that it is quite difficult to keep
up with it all.
What stands revealed is a space program characterized by decades of supporting
re-search and development. long-term plan-ning, constantly increasing support, and
excellent engineering.
This is confirmed by the unveiling of the standard Soviet space launch vehicle
- "carrier rocket," in their terminology - at the Paris Air Show held at le Bourget
on May 26, 1967. At the same time, the Soviets revealed details of the rocket engines
used to power their vehicles. This has been followed in 1968 by additional photographic
and motion picture film releases from Tass and Sovfoto, as well as from the Czech
news agency (CTK). This evidence, in turn, confirms the fact that the Soviets developed
and used a large launch vehicle during the first decade of the Space Age.
The standard Soviet space launch vehicle is undoubtedly the original T-3 ICBM.
This conjecture is supported by the early 1957 flight history of the T-3 ICBM as
announced by the Soviets and revealed by our long-range Turkish-based tracking radars.
Briefly, the history of the Soviet space program goes back to 1903, the year
of publication of the initial works of Kon-stantin E. Tsiolkovski dealing with the
use of multi-staged rocket-propelled space vehicles. In 1919, the first Soviet rocket
research laboratory, the Leningrad Gas Dynamics Laboratory (LENGIRD) was established.
The Soviets were flying their first liquid-propellant sounding rockets in the 1930's.
They received a windfall (as we did) in 1945 with the capture of the German rocket
research center at Peenemunde, the German A4 (V -2) assembly factory, Mittelwerk,
near Nordhausen, and several hundred German A4 rocket production and test
engineers. The USA got von Braun's design and development team. By 1949, most of
these German rocket engineers had been returned to Germany by the Soviets, who
had, in the meantime, cranked-up the A4 production line again. Several improved
versions of the A4 were developed by the Soviets. But, by and large, their
rocket development work remained
their own; they learned from the Germans and then modified their own developments
from this teaching.
We can lay to rest forever the fallacy that the Soviet space program was German
in origin and execution. Facts no longer will support this notion.
Both the Soviet Union and the United States started serious design studies of
a nuclear-tipped ICBM at about the same time. The USA demurred from building the
very large rocket vehicle that would have been required to carry the bulky and heavy
nuclear and thermonuclear war-heads of 1950-1952. The Soviets went ahead and built
the kind of big rocket it would take to deliver such a heavy warhead over intercontinental
ranges. We waited until the "thermonuclear breakthrough" of 1953 permitted smaller
TN warheads and there-fore smaller ICBM's of the size of the Atlas SM-65. By 1957,
the Soviets found themselves with a very large rocket capable of carrying very heavy
payloads over both ICBM range and into orbit.
Based on the data filed with the FAI in Paris for the Soviet manned flight rec-ords,
we believed that the Soviets had developed some very large liquid propel-lant rocket
engines. The Soviet data sub-mitted to FAI clearly states that the launch vehicle
was powered by six rocket engines. To achieve the payload orbiting capability announced
by the Soviets, this meant that the rocket engines would have to be large. In
US terminology, a rocket engine is a single combustion chamber with a single turbo-pump
supplying its propellants. There have been some exceptions to this, namely the RMI
XLR-11 four-chambered "Black Betsy" that powered the Bell X-1, the Convair MX-774,
the Douglas D-558-2, and the early version of the X-15.
But, to the Soviet engineers, a rocket engine was one or more combustion chambers
linked together to be supplied by a single turbo pump. This follows the same logic
that terms a V8 automobile engine as an engine, although it may have eight separately
acting combustion cylinders; a V8 automobile is not powered by eight separate engines,
by definition.
This glaring difference in rocket terminology which caused some observers to
conclude that the Soviets were either lying, or had big combustion chambers available,
was resolved when the standard Soviet space vehicle was displayed at Paris. According
to Soviet terminology, this launch rocket does indeed have six rocket engines as
follows:
Four main thrust chambers and two vernier chambers with a single turbo pump in
each of four strap-on boosters. This is known as the RD-I07 rocket engine. Four
main thrust chambers and four vernier chambers with a single turbo pump in the central
sustainer core, known as the RD-108 rocket engine. A single thrust chamber and four
vernier chambers with a single turbo-pump in the top stage. This engine designation
is unknown, but may be the RD-119.
Totals: four boosters, one sustainer, one top stage. Six rocket engines in all,
Soviet style, and six turbo-pumps.
In operation, the Soviet carrier rocket is a 1% stage vehicle with a series top
stage. As we will see, the top series stage was added to the basic booster as the
program progressed. According to Space Business Daily, the Soviets refer to this
carrier rocket as the RD-107, the same designation as the booster engines.
At lift-off, it operates as a parallel-staged vehicle. The four RD-107
engines of the boosters and the RD-108 of the sustainer core are ignited at the
same time. This is a total of 20 main thrust chambers and 12 vernier chambers,
providing an estimated total takeoff thrust of 950,000 lbs., increasing to
1,150,000 in vacuum. At an undisclosed time and altitude, the four strap-on boosters separate from the
sustainer core, probably by having explosive bolts sever the fore and aft attachments.
The hammerheaded sustainer core continues thrusting with its RD-108 engine producing
228,480 lbs. of thrust. In due course - thrust duration unknown - the sustainer
core propellant tanks are emptied, and the RD-108 shuts down. If the vehicle is
carrying its top stage, the single-chambered top stage engine then lights-off with
"fire-in-the-hole" technique, and explosive bolts separate the top stage from the
interstage truss structure.
Soviet rocket technology must certainly be applauded if their engineers can man-age
to ignite simultaneously 32 thrust chambers at launch. The ignition technique is
very similar to that of the German A4, as shown by released motion pictures of the
start sequence. At the ignition signal, propellant valves open permitting the propellants
- liquid oxygen and kerosene - to flow to all combustion chambers by a combination
of gravity feed and tank pressurization. We don't know whether ignition is accomplished
by pyrotechnic igniters in each chamber or by use of "hypergolic leads" - slugs
of propellants introduced into the engine plumbing between tanks and chamber injectors
so that when they initially come into contact after the start signal, they start
a fire simply by contact with each other. Thus, in this "preliminary stage," a very
low-thrust combustion process gets ignition going in all 32 thrust chambers.
Using either instruments to detect combustion in all chambers or eyeball inspetion
through periscopes from the block-house, the launch crew has a few seconds to determine
if all chambers are lit off satisfactorily. If everything is well, the "main stage"
signal is sent, starting the turbo pumps. Thrust in all chambers then rises rapidly
to some 950,000 lbs. total because the propellants are being driven into the combustion
chambers by the turbo pumps. Once thrust has risen to the correct level, four launcher
arms swing back from their hold-down attachment points at the forward booster attachments,
leaving the vehicle free to lift off at an acceleration of about 1.3 gees, which
is nearly optimum.
Unlike our paper-thin Atlas vehicle which also uses a modified 1%-stage principle
- jetissoning only two outboard booster engines, however, instead of engines and
tanks - the Soviet carrier rocket is built very solidly. While the vehicle was being
assembled at Paris, technicians walked up and down all over it. It was lifted and
placed on its railway car erector by two cranes which picked it up and the forward
and aft booster attachment points. By using the strap-on booster concept with parallel
staging, the Soviets were able to make a much shorter vehicle than would have been
possible with series staging, and the carrier rocket is therefore a much stiffer
vehicle than our smaller Atlas. There is also evidence that Soviet engineers paid
a great deal of attention to aero-dynamics in their design.
This sustainer-booster combination is undoubtedly the first-generation Soviet
ICBM, often termed the T-3 and also called the M-108, although the latter
designation may have referred only to an earlier version of the RD-107 rocket
engine. As such, the sustainer-booster combination alone launched the first
three Sputniks without a top stage. Soviet photos have been released showing the
launching of Sputnik III with no top stage and no interstage support trusses.
Another photo has been released showing a top stage and interstage truss
structure with the caption, "Launching
of the Soviet pioneer manmade earth satellite." Therefore, the exact configuration
of the launch vehicle for the first three Sputniks is, at this time, unconfirmed,
but the standard Soviet space carrier rocket was indeed used to launch the Sputniks.
Although the spherical Sputnik I was only 24" in diameter and weighed 184 lbs.,
it is not generally known that the Soviets orbited a total of some 8,000 lbs. on
the first shot. Sputnik II weighed in at 1,120 lbs. with the dog Laika aboard, and
again some 8,000 lbs. were orbited. Sputnik II was a bright object in the heavens,
and I watched it go overhead many times. Sputnik II was photographed from Cape Canaveral,
and RCA Service, Inc. estimated its length between 74 and 84 ft. The Royal Aircraft
Establishment in England estimated from tracking data that the entire Sputnik II
vehicle was 7.6 ft. in diameter and 65.6 ft. long. The total length of the carrier
rocket sustainer core plus Sputnik II payload shroud is actually between 95 and
110 ft. long (depending upon whether or not the top stage structure and interstage
trusses were really used), which is very close to the photo-based estimates of 1958.
The first three Sputniks were therefore orbited using only the booster-sustainer
configuration without any top stage. With Sputnik I, the rocket was operating far
below its maximum payload-carrying capability. Even with the 2926-lb. Sputnik III,
the vehicle was operating far below the 3087-lb. orbital capability of the booster,
a figure recently revealed by Soviet pro-fessor G. V. Petrovich.
In 1959-1960, the Soviets added the top stage to the RD-I07, and this was first
tested on the launching of Luna I on January 2, 1959. This, then, was the complete
2½-stage booster that was eventually to launch the manned Vostoks. Petrovich announced
recently that the orbital capability of this booster was 10,143 lbs., and this was
very close to the weight of Spacecraft I, launched May 15, 1960, which put an unmanned
Vostok into orbit for the first time.
The Soviets did not go at their manned orbital program lightly. There is absolutely
no substantiation at this time to the persistent rumor that the Soviets lost one
or more cosmonauts in the Vostok program. When they finally did lose a man, Komarov,
in the first Soyuz flight, they did not try to hide the fact. They even went to
great lengths in the unmanned Vostok test program to keep the West from believing
that they had a cosmonaut in orbit; for the test of the communications in one of
the unmanned flights, they deliberately used a recording of a choral group singing
folk songs rather than the recorded voice of a single man. The Soviets do have a
sense of humor, because they have admitted with chuckles that they also thought
that this chorus from space would cause a bit of confusion among Western listeners!
They also used their most reliable orbital weight-lifter as the launch vehicle,
the standard carrier rocket. By the time they orbited the first unmanned Vostok
in May 1960, they had had at least six tests of the vehicle as an ICBM (probably
more), three orbital Sputnik shots, and three lunar shots. Their Vostok program
was not without problems, however. Technology is technology, and there are no infallible
super-engineers. They lost Spacecraft I, which is still going around in orbit as
an unmanned Vostok. Spacecraft III, another unmanned Vostok precursor flight, burned
up on re-entry. However, by the time their carrier rocket was "man rated," at the
time of the first manned flight, the Soviets had had at least 18 space launches
(that we know of) with the carrier rocket, two of which failed (that we know of).
Undoubtedly, there were more flights of the vehicle than that, some of them being
the Pacific test shots that were run during that time period. Therefore, the Soviets
had a man-rated launch vehicle of very high reliability by the time Yuri Gagarin
climbed aboard and rode into history once around the world on April 12, 1961.
Having available the large standard carrier rocket, the Soviets were not as
limited in the weight of their manned spacecraft as was NASA with the Mercury
spacecraft lofted by the Atlas-D. The nominal orbital weight of the Vostok spacecraft, in-.
eluding pilot, is given by the Soviets as 4725 kilograms (10,422.5 lbs.) . Therefore,
they did not need to cut things as finely as the USA did with Mercury. The Soviets
could afford the weight of a dual-gas-oxygen and nitrogen - capsule atmosphere,
plus enough consumables to permit Vostok to remain in orbit for long periods of
time - 64 orbits in the case of Nikolayev in Vostok 3. They even had television
transmission from the Vostok.
The Vostok capsule is a very strong and rugged vehicle, as evidence by the released
photographs. It also came as a great surprise to Western engineers to see from released
motion pictures that the Soviets do not use "white room" techniques in the assembly
and check-out of the Vostoks. Photos plainly show the Vostok capsules being assembled
in huge hangars. The equipment aboard is also very rugged and heavy; a photo shows
a coveralled Soviet technician installing some electrical gear with a large 250-watt
soldering iron.
The Vostok capsule that is placed in orbit consists of 1) the entire top stage
of the carrier rocket, 2) a service module carrying electronics, consumables, and
re-entry rockets, and 3) a spherical re-entry com-mand module. An aerodynamic shroud
protects the spacecraft during launch and perhaps is jettisoned after separation
of the top stage from the booster sustainer core.
The only thrusters visible on the Vostok spacecraft that have been displayed
in Paris, Moscow, and Montreal are the four nozzles located on the aft end of the
top stage. These may also be vernier rockets for final orbit adjustment. They appear
to be canted slightly to provide roll control as well as pitch and yaw control when
operated singly or in pairs.
When ready for re-entry, the top stage is jettisoned, revealing the conical-shaped
aft end of the service module. This has never been displayed, but is shown in both
Czech and Polish drawings. Although its exact shape is therefore open to question,
it must also mount some manner of attitude control thrusters to align the command
and service modules for proper re-entry rocket firing angle. The re-entry rocket
engine is apparently at the small end of the conical frustum of the service module.
After firing of the re-entry retro rocket, the service module is separated from
the spherical command module, prob-ably by releasing the straps that go around the
command module. The service module thrusters, wherever they are located, may also
impart a roll to the command module after it is positioned in the proper re-entry
attitude.
The command module is a sphere 96" in diameter. The displayed Vostok had a coating
of aluminum foil over the sphere to provide thermal control. Released Soviet photos
indicate that the sphere is coated with an ablative heat shield material on the
hemisphere at the pilot's back, while the remainder of the sphere is protected with
honeycomb material.
Early USA manned capsule designs used the spherical shape, but this was later
modified to the blunted cone shape now so familiar to us, primarily because the
blunted cone shape weighs less. The Soviets stuck to the spherical re-entry shape
because: a) they did not have a weight-lifting problem to contend with, and b) the
aerodynamic characteristics of a sphere are very well known. In the engineering
trade-off between weight and aerodynamic knowledge, the Soviets opted for more weight
and a shape they knew more about, thereby shortening their development time period.
The Vostok re-entry sphere has an off-set center of gravity to provide some stabilization
during re-entry. It may also have an imparted roll around its fore-and-aft axis
(with respect to its position on the launch vehicle). It apparently has no drogue
parachute like our Mercury and Gemini capsules. It comes in like a spinning ball.
The spherical shape, with its off-set CG and imparted roll, leads me to believe
personally that the Vostok probably undergoes more oscillation during re-entry
than the US space capsules. Re-entry in a Vostok must be a wild ride!
At about 23,000 ft., the cosmonaut ejects from the spherical capsule. The entry-exit
hatch blows off, and the three ejection seat rockets fire to push the cosmonaut
and his seat clear of the falling capsule. The cosmonaut then separates from his
seat and lands under a regular personnel parachute, just like a jet pilot that has
ejected from a plane. Soviet films show the Cosmonauts practicing ejection from
Yak-25 Flashlight jets. At about 16,000 ft., another hatch blows off the side of
the Vostok sphere, the capsule recovery parachute deploys, and the capsule lands.
at a velocity of about 33 ft. per second.
Although all Vostok cosmonauts used this type of landing system, the Soviets
claim that a landing can be made with the cosmonaut remaining inside the capsule.
This may be true; in an emergency, the cosmonaut may not have to eject from the
capsule. But it is my belief that such a landing would be very rough on a cosmonaut.
Why did the Soviets use this recovery technique for their Vostok cosmonauts?
In the first place, they recover their capsules over land rather than over water
as the U. S. does. Impact forces for a ground landing are much more severe than
for a water landing. The geometry of the Vostok sphere shows that the only available
free Volume in the sphere for stowage of the capsule parachute is on the side of
the sphere. If the cosmonaut stayed inside the capsule, he would have to take the
parachute opening shock and a landing shock of 33 ft. per second on his side. So
the obvious safe technique was to get the cosmonaut out of the capsule before parachute
opening and landing. This also permitted a smaller capsule recovery chute and the
high capsule landing velocity.
Again, however, we see Soviet engineering philosophy at work here. The cosmonaut
is already strapped into an ejection seat which is required for emergency egress
during a launch abort. The Soviets did not develop an escape rocket system such
as we used on Mercury. They used the ejection seat technique that we later used
with Gemini. Apparently, the Soviet engineers decided to use the ejection seat that
was incorporated for launch abort purposes in a dual role: launch abort safety as
well as simplifying the landing problem.
The ejection seat is also obviously intended for launch abort purposes because
the capsule's aerodynamic shroud has a large, unfaired opening in it for entry and
egress.
Although the Vostok spacecraft system may appear to some people to be crude,
it is well to remember that it worked quite well. The Soviets got 12 flights with
it, in-cluding six completely successful manned missions. They even flew a woman
in it. Soviet engineering, as evidenced by their aircraft alone, is eminently pragmatic.
Their launch pad technique also shows this. Recently released motion pictures
of the check-out, erection, and launch sequences at the Tyuratam Cosmodrome reveals
an entirely different system than that in use in the United States for large launch
vehicles.
The carrier rocket is completely assembled horizontally on a railway car erector
inside the Cosmodrome hangar. The Vostok space capsule also undergoes final assembly
in the hangar and is put through a series of systems tests with and without a cosmonaut
aboard before mating the spacecraft to the booster. Finally, the entire carrier
rocket and spacecraft is mated horizontally in the hangar. The check-out vehicle
is taken by rail on its erector car to the launch pad. It is then erected on the
pad by the hydraulically-operated erector, and four counter-weighted steadying and
hold-down arms swing in to secure the booster vehicle on the pad in a vertical direction.
These hold-down arms also have work platforms attached to them. Two swing-back umbilical
towers are also positioned against the vehicle so that propellant loading lines,
electrical cables, and capsule air conditioning ducts can be attached. After the
erector is removed, a rail-mounted service tower with an elevator is moved into
position on the erection side of the vehicle. The vehicle itself does not have its
base flush with the main surface of the pad, but is positioned with its base below
the pad level in a well over the flame pit. There are no assembly operations carried
out on the launch pad, but some final systems checks are probably made. Everything
appears to be moved in and out of the launch pad area by rail.
Either the Soviets have two such pads at Tyuratarn Cosmodrome, or this system
of horizontal hangar assembly and rail-borne erection has been designed for an extremely
rapid pad turn-around time. The first Soviet paired flight with Vostok 3 and Vostok
4 required two launches within 24 hours - one on August 11, 1962, and the second
on August 12th. It took the U. S. a week of three-shift operation to recycle the
launch pad between Gemini 7 and Gemini 6; this long recycle time was due to the
fact that the Gemini-Titan vehicle must be assembled in a vertical position on the
launch pad before final systems checks can be done.
If the Soviets used the same launch pad for their paired Vostok flights, it seems
unlikely that the USA can match their pad turn-around time even with the Saturn
V Complex 39 or the Titan III complex at Cape Kennedy. Obviously, the Soviets can
assemble and check-out two Vostok launch vehicles at the same time with their hori-zontal
assembly system.
Now that the Soviet Sputnik, Lunik, early interplanetary, and Vostok programs
have been reasonably well described by Soviet sources and Western analysts, what
about the Soviet multi-man Voskhod follow-on program? Again, we now know from Soviet
sources that the standard space carrier rocket was used. This has been called the
RD-107B vehicle by some U. S. sources. It utilizes the same 1½-stage booster-sustainer
vehicle, but has an uprated, lengthened upper stage that is some 18 ft. longer than
the Vostok top stage. Most of this additional Volume is devoted to additional propellants,
and the new top stage may have a multiple-chamber rocket engine in place of the
single-chamber engine of the Vostok vehicle. The released photographs at the time
of this writing give no information on this point. However, like the Vostok RD-
107 vehicle, the Voskhod RD-107B rocket was used by the Soviets from 1961 on. According
to Professor G. V. Petrovich, it has an orbital capability of 14,333 lbs. The Voskhod
shroud seems to be the same diameter as the Vostok's, but it is longer.
External details of the Voskhod spacecraft itself have not yet been revealed
at the time of this writing, but several things can be inferred about Voskhod. It
has no ejection seats in evidence. In Voskhod 1, the three cosmonauts Komarov, Yegorov,
and Feoktistov flew without pressure suits and landed inside the capsule. On Voskhod
2. Belyayev and Leonov flew in pressure suits as a safeguard against airlock mal-function,
the weight of the third crew member being replaced by the collapsible airlock for
Leonov's EVA. Again, Voskhod 2 landed with the two cosmonauts aboard. The Soviets
have announced that retro-rockets were used in the landing sequence.
The simple blackboard drawings of Leonov during the press conference in which
he described his EVA indicate that the Voskhod may still be the 96-inch diameter
re-entry sphere of the Vostok program but with a canister added on the forward end
for a larger landing parachute. Since the cosmonauts landed in the capsule, it seems
reasonable to assume that the Soviets eliminated the side-mounting of the Vostok
recovery chute. How and where landing retro-rockets could have been mounted so that
they were protected during re-entry remains unknown at this time.
Whatever the Soviets have come up with beyond Voskhod is not known yet. Undoubtedly,
they have already made several unmanned flights with a much larger car-rier rocket,
if the past history of their space program is any indication. Proton 1 was flown
on July 16, 1965; its announced weight was 26,840 lbs. in orbit. As displayed in
Paris, Proton 1 was 14.76 ft. in diameter. A vehicle of this size and this weight
would require a launching vehicle of a size between Saturn-Ib and Saturn-V. The
Soviets may have used this new vehicle for the successful Venus shot, and may also
have used it for the ill-fated flight of Soyuz 1 on April 24, 1967 during which
Komarov lost his life after re-entry. Norman Baker, the editor and publisher of
Space Business Daily, remarked to me that the Soyuz booster might be an SS-9 core
surrounded by four strap-on SS-9 boosters.
The SS-9 is the new Soviet ICBM paraded in Moscow in 1967 and powered by a cluster
of six thrust chambers. This would certainly be consistent with the Soviet space
vehicle design philosophy evidenced to date. However, all of this must remain speculation
until more details are released by the Soviets and until they make their next series
of space flights.
One thing is certain: The Soviets are going to continue to expand their space
program with multi-man flights, orbital rendezvous, and very large launch vehicles.
The Moon may not be their immediate goal; a permanent manned orbiting space station
may well be in the Soviet space planning instead, and this may be used as a departure
point for the Moon and the planets which they are currently engaged in scouting
successfully with unmanned spacecraft.
The Soviet Union has been aiming toward space flight longer and more consistently
than the United States. It would be folly to believe that they would not continue
the pace of their program regardless of what the United States does.
