From the spark that was Nikolai Tesla wowing the crowds of New York’s Madison Square Garden with his four-foot long, steel-hulled, radio-controlled boat (patented in 1898) and his follow-on “dirigible wireless torpedo,” we are now going on 125 years of unmanned surface and subsurface vehicles, with an easy bent towards using them in warfare.
With stops at the German Fernlenkboot (FL) of the Great War and the Italian Motoscafo da Turismo (MTS) unmanned explosive motorboats of WWII, today’s maritime lingering/loitering USV munition has been well proven in the Black Sea.
Following up on the dramatic attack late last month on the Russian 4,000-ton Admiral Grigorovich-class frigate Admiral Makarov and smaller Natya-class minesweeper Ivan Golubets by Ukrainian USVs more information on these “killer kayaks” have surfaced including an excellent photo essay that has popped up on Reddit of no less than a half-dozen of these little black boats under construction and testing, including design details and the mix of commercial-off-the-shelf components and local supplies (Rotax 3-cylinder engines from a Canadian Sea Doo jet ski– which only run about $2-3K each— a Starlink receiver, old Warsaw Pact-era contact exploders, et. al).
H.I. Sutton over at Covert Shores, who has been covering these boats since the beginning, has compiled this rough specs list for these crafts which reportedly cost a bargain of just $250K each (as opposed to an MK-48 Mod6 torpedo which runs $10m in its current format):
Length: 5.5 meters
Full weight: up to 1,000 kg
Operational radius: up to 400 km
Range: up to 430 NM (800 km)
Autonomy: up to 60 hours
Combat load: up to 200 kg
Max speed: 43 knots (80 km/h)
Navigation methods: automatic GNSS, inertial, visual
Video transmission: up to 3 HD video streams
Crypto protection: 256-bit encryption
Odds are, Tesla can feel the connection.
