Following the Falklands war, British Aerospace explored the Skyhook, a new technique to operate Harriers from smaller ships. Skyhook would have allowed the launching and landing of Harriers from smaller ships by holding the aircraft in midair by a crane; secondary cranes were to hold weapons for rapid re-arming. This would potentially have saved fuel and allowed for operations in rougher seas. The system was marketed to foreign customers, and it was speculated that Skyhook could be applied to large submarines such as the Russian , but the system attracted no interest.
