Does anyone have any information, design designations, drawings and specifications on the designs submitted in the 1958 US Navy competition, that lead to the Lockheed P-3A Orion Anti-Submarine/Maritime Patrol Aircraft being declared winner?

Hmmm. 4 years on, can we answer this question? Renamed topic to include relevant Type Spec.

"Code One" magazine - August 2012 mentions
contenders from Martin and Consolidated in the competition.
No more info in the article I think...

The P-3 came about as a response to Navy Type Specification #146 issued in 1957 for a new land-based antisubmarine warfare, or ASW, aircraft to replace the Lockheed P2V Neptune land-based maritime patrol aircraft and the Martin P5M Marlin flying boat. Very specific requirements pertaining to delivery schedule and cost constraints dictated the need for adapting an off-the-shelf aircraft design for the maritime patrol mission.
The competitors were Martin, Consolidated, and Lockheed, three companies that had been building patrol aircraft for the Navy for more than three decades at that point. The French Atlantique, developed with the help of US Navy funds, did not meet the stated range requirement and was eliminated from the competition.[...]

Friedman, in "Network Centric Warfare", describes the Orion's role as an interceptor, to exploit the revolutionary capabilities of SOSUS. Hence, I suspect, the requirement for a higher efficient cruising speed than the P2V.

The interesting question is which off-the-shelf platforms Martin and Convair had to work with. A Super Mercator? A CV-880 ASW?

I'm fairly sure that Convair proposed the P6Y and Martin the P7M .

Enjoy the Day! Mark
