velocity better than 1,200 miles per hour. The missile is radar 
euided, and its kill rate is high. This missile has the lethal power 
to stop any aircraft. 
Two of the newer missiles in this category are the Navy’s Sparrow I 
and the Sidewinder. The Sparrow, now operational in the fleet, is 
powered by a solid motor and is radar guided. The accuracy of this 
missile has been demonstrated against other aircraft and missiles. 
There are currently two other versions of the Sparrow, the Sparrow 
II and the Sparrow III. It has been reported that the Sparrow II 
will replace the Canadian Velvet Glove. 
The Sidewinder is another naval air operational missile. It is 9 
feet long and 414 inches in diameter. The powerplant is a solid- 
propellant motor. Guidance is infrared homing. The range is ap- 
proximately 5 miles and currently the kill rate is said to be 7 out of 
10. It is reported that the Navy intends to replace the Sparrow I 
with the Sidewinder. 
There are three other missiles in this category that should be men- 
tioned. The first is the Ding-Dong, a liquid-propelled missile capable 
of carrying atomic warheads. Little is known of this missile, but 
it is said to be in the advanced stages of development. The second 
is the Diamondback. The performance of this missile is not known. 
Finally, the third is the Navy’s Zuni. The Zuni is an air-to-air or an 
air-to-ground missile. It can be used in conjunction with high-per- 
formance fighters and attack-type aircraft. It can be used against 
other aircraft as well as against such ground targets as tanks, gun 
implacements, etc. 
In the air-to-surface category the Navy seems to be particularly 
active, especially in antisubmarine applications. In the past decade 
the Navy has had more than six missiles in this family, although it is 
not known whether any are currently operational. The Tiny Tim is 
the best known of this category. Since the Tiny Tim, there have been 
the Petrel, Dove, Goose, and Duck. 
More recently, the Navy has been evaluating the Bullpup, also an 
air-to-ground missile. It is expected that this missile will soon join 
the fleet. The missile is approximately 11 feet long and a foot in 
diameter. It is powered by a solid-propellant motor. The Bulldog, 
a larger improved version of the Bullpup, is also a solid-propellant 
missile in this class. 
Finally, one of the newer Navy air-to-surface missiles is the Corvus, 
designed for use on carrier-based aircraft. Its current status is un- 
known; however, it is known that the missile’s aerodynamic character- 
istics have been evaluated through wind-tunnel tests. 
As far as the Air Force is concerned, they have only one missile in 
the air-to-surface class, the Rascal. The Rascal is approximately 35
