Subj: F8U-3 Airplane; Improved Radar for
1. On 14 August CVA presented a technical report on a program to provide an improved radar for the F8U-3 (available 35th airplane and subsequent) which will increase detection range by 40% and provide the airplane with a head-on attack capability against a 1.6 M bomber.
2. The major changes to the APQ-74 radar and the airplane required for the improved radar are as follows:
a. Replace present 24" antennae with 34" antennae.
b. Relocate radar set package aft of pilot's cockpit in order to accommodate larger antennae within existing nose lines.
c. Remove 82 gallon capacity fuel tank. The specification fuel is 2036 gallons. Current estimated fuel capacity is 2138 gallons with 3½% allowance for design changes and manufacturing tolerances and 3% for temperature expansion.
3. Since the proposed radar improvement significantly enhances the capability of the F8U-3 for an apparent modest change in the radar and the airplane, the proposal is received with considerable interest and will be studied in detail for an early decision.
4. CVA proposals for potential development of the F8U-3 to provide an attack capability and performance increase to the 2.5-2.7 M range are impractical and have not been received with interest in the Aircraft Division.
