1/700 USS Los Angeles class, Flight 1 with towed array sonar (N700142)
The model reproduces the Flight 1 of the Los Angeles-class submarines after the introduction of towed array sonar (Boston SSN-703). Early submarines were also retrofitted with it. You may find a second screw in the model. This is an experimental 11-bladed vortex dissipater propeller tested in the late 1970s.
