ROCKETRY—COX AND STOIKO Date 
The first-stage propulsion system is a liquid-propellant rocket engine 
utilizing liquid oxygen and kerosene as propellants. The engine 
thrust is rated at approximately 254,000 pounds. It should be noted 
that the second stage of the T-2 is basically the T-1 (engine thrust 
77,000 pounds). 
The second of the Army’s intermediate-range vehicles is the T-4. 
The T-4 is still another version of the German V-2, differing only by 
the addition of wings. This vehicle is a production item and is com- 
monly known as the winged T-1. It has the same engine as the T-1 
and a reported maximum range of 1,000 miles. This missile is also 
recognized as a test bed for the T-4A, hypersonic glide bomber. 
In order to evaluate fully and accurately the Russian missile 
capability, the Soviet naval missile arsenal must be taken into con- 
sideration. It is most generally known that the Soviet Navy is well 
equipped for missile warfare. Its submarine fleet is said to number 
between 400 to 800 operational vessels with an additional 100 under 
construction. In addition to the vast submarine fleet, the Soviet 
Navy is being equipped with several types of missile ships; for ex- 
ample, antiaircraft and short- and medium-range missile attack ships. 
United States Naval Intelligence has admitted that the Soviet Navy 
is second only to the United States Fleet in numbers and is growing 
very fast. 
Probably one of the most potentially dangerous weapons systems 
that the Russians can deploy against the United States and the Free 
World is their growing submarine fleet, coupled with their under- 
water-launched ballistic missiles. Of the several techniques available 
for launching missiles underwater, in all probability a modified ver- 
sion of the deadly German V-2 submersible ballistic missile launcher 
would be used. In the older German plan, three V—2 missiles in their 
containers could be towed horizontally and underwater by one sub- 
marine at approximately 15 miles per hour from German seaports to 
any coastline, depending only on the cruise capacity of the submarine. 
Once on location, and to ready the missile for launching, the ballast 
end of the container was to be flooded, forcing the container into the 
vertical position. When in the upright position, a built-in gyroscope 
system would hold the container in the desired launch position by 
counteracting any yaw or roll movements. The missile container 
was to be outfitted with a control station and propellant tankage in 
addition to the necessary servicing equipment. The weight of the 
container and missile was about 70 tons, of which the missile and pro- 
pellants represented about 35 tons. After the necessary prelaunch 
servicing, the missile was to be remotely fired from the mother 
submarine. 
When the Russians took Peenemiinde, they acquired this fantastic 
weapons system which was then ready for production!
