Summary
| Description |
The U.S. Navy radar picket submarine USS Spinax (SS-489), in 1947. USS Requin (SS-481) and USS Spinax (SS-489) were completed as radar picket submarines in the fall of 1946. Although not yet classified as radar pickets ("SSRs"), both submarines mounted high-powered SR-2 search radars and SV-2 height finders directly on their afterdecks, with the radar electronics and CIC just below in the after torpedo rooms. Although a stern launching capability was still retained, the tubes had to be loaded externally. To accommodate the additional electronics, each boat received an extra motor-generator and more air-conditioning, and to provide a reference point for the combat air patrol (CAP) they controlled, homing beacons were deck-mounted on both. Despite having to discontinue radar operations whenever they submerged, Requin and Spinax were basically successful in their new roles, and they were certainly more survivable than a corresponding destroyer. However, the low deck-mounting of their antennas severely limited radar performance and attracted reliability problems from both breaking seas and salt-water intrusion into the waveguides. (USN) |
