The shipboard equivalent of the GP series of transmitters is the TCE series.  It is slightly larger and uses steel for the chassis & covers.  The surprising thing is that the TCE also requires 600 to 800 cycle power (in addition to 28 volts DC).
Go figure.
My memory says that the preliminary GP-7 manual indicated that the 800 cycle power source was an 800-1 inverter.  These inverters were reputed to be at least as good sirens as they were inverters.
