The Swedish Gotland class of submarines are well suited for both littoral and open ocean operations, having the first operational AIP (Air Independent Propulsion) system, a system which utilizes a Stirling closed-cycle engine for underwater operations and conventional diesels on the surface. but The Stirling combusts a mixture of liquid oxygen and diesel fuel to power a generator. The Gotland was seconded to the United States Navy to help the USN improve tactics against diesel-electric subs, during this time, HMS Gotland achieved a "kill" on the USS Ronald Reagan (CVN-76), proving the efficacy of diesel-electrics today.

A standard OKB sub; single piece full hull, cast on a central sprue, and a separate resin prop hub. The hull of the sub has some slight machining/sanding artifacts, but some light sanding should smooth it out nicely.

Two small photoetch frets are included; a seven-bladed scimitar prop, and a fret with a display stand.

Available from Pacific Front Models, this kit retails for $17.95. Thanks to OKB for this review sample.
