TOP SECRET,
U-2 Vulnerability Tests
Vulnerability of the U-2 was tested against the '-102 and -104 fighters at
Eglin AFB in December 1958. The tests were conducted under optimum
controlled ground and air environment for the attacking pilot (i. e., out-
standing pilots, isolated air space, ideal weather, pre-selected intercept
point, etc. ). The F-104 cannot cruise at altitudes over 60, 000 feet, but
it possesses a capability to convert speed to altitude and attain co-altitude
of the U-2 for a period of less than 30 seconds. The F-104 was equipped
with air-to-air missiles of the infra-red seeking variety and airborne radar
that locates the aircraft and allows the pilot to visually acquire the target
to complete the attack. The F-104 radar malfunctioned at high altitudes.
The pilot of this fighter could not visually acquire the target in sufficient
time to solve the fire control pr oblem. The F-102 all weather fighter con-
sistently acquired the target and was able to solve the fire control problem
for launching air-to-air missiles. To be successful, the missiles require
outstanding high altitude performance and a slant range in excess of five
miles,
The performance of both aircraft exceeded the present capability of opera-
tional Soviet fighters. The standard operational Soviet fighters cannot
attain co-altitude of the U-2. A new fighter, the Fitter, of which an estim-
ated 120 have been produced, is considered capable of co-altitude for a period
of several seconds. It is not, however, presently considered operational.
The standard Soviet all weather fighter, YAK-25/Flashlight, is considered
capable of acquiring the U-2 on airborne radar. However, to complete a
successful intercept would require an air-to-air missile with a slant range
in excess of seven miles. The USSR is considered to have air-to-air missiles,
however, there is no intelligence source that indicates that the missiles are
operational.
Conclusions
1. The F-104 can attain co-altitude, but the difficulty in visually acquiring
the target makes any single attack a low probability of successful intercept.
2. The F-102 with its radar can acquire the U-2 and possesses the perfor-
mance to solve the fire control problem, however, air-to-air missiles of
outstanding performance and long range are required to accomplish airborne
intercept. There is no known operational deployment of air-to-air missiles
by the Soviets.
3. Successful intercept of the U-2 by the Soviet defensive fighters for the
next few months is unlikely.
