money and a new DARPA Director who had other priorities.

Wonder why nobody went back to the XF5U/V-173 "Flying Flapjack" design for this. While I don't think it could ever take off vertically, I'm pretty sure it could take off with ~30knots wind over the deck. Just time the takeoff for when the ship turns to put the wind about 30deg off the direction of motion. I know it could hang off the props for a vertical landing, or do a super STOL landing with maybe 50ft forward roll.

Single T700 or so class engine (~2500hp), Currie Industries 9" ring and pinion with 2.73:1 gear reduction to turn 6000rpm at the engine to 2200rpm at the drive shafts, H53 90deg tail rotor drive gearbox.

While this was indeed the aim, as far as I know, this was never demonstrated with the V-173, I assume due to lack of power, and of course, the XF5U prototype never flew . . .

cheers,
Robin.

I did not realize they had gotten that far with a prototype. To bad it did not get into the air.

DARPA picks six firms to develop experimental ship-launched drones

ANCILLARY would take off vertically from a ship's flight deck and then shift to forward flight to conduct recon, move cargo, or track enemy targets at sea.

Still surprised that nobody has used the XF5U shape for the TERN drones...
