Original Note by the Book’s Owner:

May 2012

These papers are from the old WECO/ATT Field Engineering “Blue Book” that I had for many years. This data will not be found in general publications, for the most part. The Germans copied most of the book which I retained as classified then, so this stuff, though old data, is still applicable to some extent.

.....1951.....

July (5)

Office Chief of Ordnance (OCO) requested feasibility study on the defense against formations of aircraft by use of Corporal in conjunction with T33 or Nike-Ajax system.

July (30)

Conclusions were reached by Bell Telephone Laboratories (BTL) that neither T33 nor Nike-Ajax were feasible to mate with Corporal.

..... 1952 .....

October (9)

Feasibility study requested by OCO for integration of an atomic warhead Into the Nike-Ajax missile system. This proposal was considered feasible, with reservations, both for the Nike-Ajax missile and for a larger-diameter missile that would make more efficient use of fissionable materials.

Nike-Hercules program reviewed by Army General Staff G-3 and G-4, Office Chief of Army Field Forces, OCO, Western Electric Co., and Bell Telephone Laboratories at Washington, D. C. Objectives of the Nike-Hercules program were defined as:

1. Development of a new missile to carry a large warhead for use with Nike-Ajax ground guidance and control equipment essentially unmodified.

2. Study of the possibilities of extended range of the Nike-Ajax ground guidance and control equipment to utilize fully the range capabilities of the new missile (Including a possible secondary role as a surface-to-surface system).

2. Ground equipment changes for the 25-mile version of the missile. It was estimated that these changes would cost about 9-1/2 per cent of the original Nike-Ajax ground equipment investment.

3. A long-range (50-mile) version of Nike-Hercules. A cost estimate for the program was given as 21 per cent of the original Nike-Ajax investment.

4. Possibilities of incorporating surface-to-surface capabilities.

Tracking antenna capabilities in high winds (based upon 521 ft-lbs to counterwind torque and 7250-lb antenna weight)

With an inflated radome (Ed FENDER SKIRTS ELEPHANT EARS) the tracking antenna will safely operate without fairings in winds up to

75 mph (approx.)

With an inflated radome the tracking antenna will safely operate with fairings in winds up to

90 mph (approx.)

With uninflated radome the tracking antenna is subject to damage in winds exceeding

70 mph

With the radome inflated no damage is sustained in winds up to

100 mph
