‘ configuration may be peculiar to o specific vehicle, ‘it should not be restricted from utilizing its capabilities for tho development of that woapon. 7 v Compatibility 16. Written guidance to the ABC members of the Group on tho subject of . compatibility states as follows: “Here it seems logical that where the characteristics of the vehicle are predominant in the problem, the responsi“bility for compatibility should rest with the builder of the vehicle.” “words are subject to two possible interpretations. These One is that the designer a tho vehicle is responsible for modifying the vehicle to make it compatible with the warhead or woapon. The alternate interpretation is that the wording, "responsibility for compatibility" implies that the control rests with tho Service having primary interest in tho weapon systom and includes also the control of development of those components of the weapon or warhoad which affect the performance characteristics of the vohicls. The Group considors the latter interpretation as the only practicable one and, consequently, fcels . : ) - , + that in such a case as that of an externally carried weapon on high speed air- ) : craft where tho shape of the aerodynamic case of the weapon mterially affects 5 C) - “the performance of the aircraft, the agency responsible for the airoraft i. development should have the prerogative of cither dictating the development ; . of or actually doveloping the case. Similarly, where the delivery techniques of the carrying aircraft or missile predominate, the fuze performance must be compatible with such delivory techniques. Compatibility will always require @ Cc compromise aclutions. It is certain that tasks in the above arcas must necessarily be the subject of separate negotiations defining responsibilities and insuring overeall integrity of design. 16. The AEC indication that military assistance is contemplatod in the area of compatibility of weapons with vehicles and suggestion that the responsibility for compatibility should rest with the bullder of the vehicle ae : 7 | when the characteristios of the vehicle predominate in the problem are con- sidered logical, particularly in view of the fact that the increasing complexities of vehicles and their systems scem to far outweigh tho difficulties in creating a satisfactory warhead.
