Teledyne Ryan 262 Manta Ray

In the mid-1970s, Teledyne Ryan built three Model 262 Manta Ray mini-UAVs for the U.S. Navy's STAR (Ship Tactical Airborne RPV) program. The goal of this program was to evaluate the feasibility of a low-observable ship-board UAV which could survive in a high threat environment and could be easily recovered.

The Manta Ray was small delta-shaped glassfibre vehicle powered by a McCulloch MC-101 engine which drove a small ducted propeller. These features ensured inherently low radar, infrared and noise signatures. The UAV was started from a compressed-air rail launcher, and could automatically fly into a net for recovery. In flight, it was controlled by a radio command guidance system. In the proposed tactical configuration, the Model 262 could have carried e.g. electro-optical sensors, radar, or electronic warfare equipment.

The flight test program in 1976/77 successfully demonstrated the fully automatic net recovery system. However, no follow-on development occured after these tests.
