The Project 945 submarines, NATO code name "Sierra," are unjustly overlooked in the model-making world. Like their predecessors in the Alfa class, the four original boats feature a titanium hull and exceptional performance. The model captain receives a submarine that, at 1.2 meters, is still manageable yet doesn't look like a toy on the water. 
 
We've broken new ground with the surface details. High-resolution resin printing creates surfaces that eliminate the need for tedious sanding. The Project 945 boasts the finest hatches, engravings, and raised surfaces. The handrails, bollards, and protective grilles are already attached to the sections. Modelers get a level of detail previously only seen in injection-molded kits. Even the mechanism of the floodgate closures has been replicated.
 
The central unit is our own pre-assembled 550 ml piston tank. Two sections are connected to it via flanges, allowing for quick assembly in a single day. Robust standard servos for controlling the rudders are located in the stern. A powerful 28 mm brushless motor provides ample thrust. Oto Gerza ( RCSUBS.CZ ) produces the markings for your Project 945 submarine, which are included in the package.
