Scale: 1/350

Set includes 36 lockers.


Caution is recommended when removing the lockers from the sprue; acrylic plastic is more brittle than the polystyrene plastic found in injection-molded plastic model kits.


This set of highly detailed, 3D-printed models represents ready service ammunition lockers for 20mm Oerlikon cannons fit to World War Two-era US Navy warships.  USS Missouri BB-63, for example, carried as many as 50 of these lockers in 1945.

Although there were many variations, this model is one of the most common of the larger types: 62" long x 24" wide x 26.5" high (not including stand).  Scaled dimensions match drawings found in The Floating Drydock's highly recommended "Fletcher Class Destroyer Plan eBook" (click here).


  • each locker measures 4.5mm long x 1.74mm wide x 1.92mm tall 
  • 10 clamps "dogs", all in the released (lowered) position
  • 4 exterior, bolt-on heat radiators
  • accurately sized and positioned radiator bolt-head detail, bolt-heads randomly turned for added realism
