Navy tests out a modern Bachstelze

Over the past few years DARPA has been working on their version of the old U-Boat kite.

ICYMI, during WWII, the Kriegsmarine’s U-boat fleet used about 200~ Focke-Achgelis FA 330 Bachstelze (English: Wagtail) aircraft. The FA330 was a type of rotary-wing kite that weighed about 150-pounds and, using an unpowered 24-foot three-bladed rotor for lift, was winched out into the air behind a U-boat on a 500-foot cable, allowing the adventuresome sailor in its single seat to have the best view on the boote.

A simple idea, they were complicated in use as they took a long time (20-30 minutes to assemble) and, if the kiteman saw an enemy warship, slowed the dive of the submarine far too long than was safe.

Well, the ONR and DARPA have teamed up to do the same thing but in an updated (and unmanned) version that swaps out the rotating kite wing for a much safer parafoil.

Observe the Towed Airborne Lift of Naval Systems (TALONS) below, a low-cost, elevated sensor mast being tested out on USS Zephyr, a 179-foot Cyclone-class patrol coastal. It is the first time it was used aboard a U.S. Navy vessel,  after being trialed on Sea Hunter, DARPA’s ACTUV vessel last year.

“Towed behind boats or ships, TALONS could persistently carry intelligence, surveillance, reconnaissance (ISR), and communications payloads of up to 150 pounds between 500 and 1,500 feet in altitude—many times higher than current ships’ masts—and greatly extend the equipment’s range and effectiveness.”
