The Combat Hornet simply extends functionality of the default Acceleration Hornet, so yes, it is usable for carrier ops. In fact, in addition to the A/A gun mode, it even adds support for carrier ILS/TACAN (111.00 MHz (47X) for the default Acceleration carrier, 112.00 MHz (57X) for Javier's Nimitz, and 113.00 MHz (77X) for Sylvain's Clemenceau).
