2Zi2 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1958 
liquid-propellant engine, and has a maximum operational ceiling of 
about 50,000 feet. The performance of this missile is somewhat com- 
parable to the U.S. Army’s Nike. Although the M-1 is now obsolete, 
it initially was pressed into service several years ago as a defense 
against the U.S. Air Force’s B-29 and B-36 bombers. 
The second missile in this category, the T-7, is a more efficiently 
performing missile based on the German World War II Wasserfall. 
The T-7 is 25 feet long and 25 inches in diameter. It weighs 38 to 
4 tons and has a maximum. altitude of 75,000 feet. Like the M-1, 
it is boost-launched and sustained by a liquid-propellant engine. The 
missile was designed to defend Russian targets against potential at- 
tacks from B-47 and B-52 bombers. United States authorities have 
confirmed that these missiles are currently in production and are 
located at missile sites around most major target areas. 
The last vehicle in the surface-to-air group is the T-8, which is 
employed as a barrage flak weapon against low-altitude targets. 
In the surface-to-surface type can be found the heart of the Russian 
military and scientific missile strength. As such, this list includes 
the medium-range ballistic missiles, intermediate-range missiles, inter- 
continental ballistic missiles, as well as the satellite-launching and 
lunar vehicles. Each of the missiles in this family is of extreme 
importance, and therefore will be discussed in some detail in the order 
mentioned above. 
There are three missiles in the medium-range, surface-to-surface 
category. These missiles are the T-1 (M-101), the S8, and the 
T-7A. The T-1 is said to be an improved version of the German 
V-2. It is estimated to be 50 feet long, 5.5 feet in diameter, and 
powered by a liquid oxygen and kerosene rocket engine. The engine 
thrust is rated at 77,000 pounds, and the range is given as 400 miles. 
The 88 is said to be another modification of the German V-2, and is 
somewhat similar to the T-1. This vehicle is specifically designed 
to be launched from underground tubes. The last missile of the 
medium-range, surface-to-surface type is the T-7A. This vehicle is 
25 feet long, has a diameter of 2.5 feet, and a takeoff gross weight of 
8,800 pounds. It is reported that the vehicle is currently in produc- 
tion and js operational. 
The Russians have four missiles in their arsenal in the inter- 
mediate range, surface-to-surface classification. Two of these, the 
T-2 (M-103) and T-4 (M-102), belong to the Army, and Comets 
I and II are Soviet Navy missiles. 
The Army’s T-2 is an improved version of the German two-stage 
A-4/A-9, which was initially designed by the Germans to bomb 
New York during World War II. The T-2 is approximately 125 
feet in length, 15 feet in diameter, and has a range of 1,800 miles.
