It was decided then that the radar would continue in spite of the fuze cancellation, and that got to be known as the 53 Echo Radar Development with the major objective of improving the Navy's ability to counter low-flying targets. The 5-inch guided projectile was in the Gunnery Improvement Program when it was first established, but the controversy and politics of having the guided projectile associated with the Gunnery Improvement Program were so great that it was finally splintered off into a program of its own. The improve- ment of the 5"/54 MARK 42 mount was part of the program, and we had a lot of trouble with the MOD 7 mount in the Vietnamese War. Part of the Gunnery Improvement Program was to upgrade that mount, insofar as possible, to the technology of the period, so it became known as the MOD 10 mount with greatly improved reliability. That has been a very successful part of the pro-.
