The Udaloy class, Russian designations Project 1155 Fregat and Project 11551 Fregat-M, are a series of anti-submarine guided-missile destroyers built for the Soviet Navy, seven of which are currently in service with the Russian Navy.

The Kirov class, Soviet designation Project 1144 Orlan (sea eagle), is a class of nuclear-powered guided-missile cruisers of the Soviet Navy and Russian Navy.

The Kirov class's main weapons are 20 P-700 Granit (SS-N-19 Shipwreck) missiles mounted in the deck, designed to engage large surface targets. Air defense is provided by twelve octuple S-300F launchers with 96 missiles and a pair of Osa-MA batteries with 20 missiles each.

The Lockheed P-3 Orion is a four-engined, turboprop anti-submarine and maritime surveillance aircraft developed for the United States Navy and introduced in the 1960s. Lockheed based it on the L-188 Electra commercial airliner.

The P-3 has an internal bomb bay under the front fuselage, which can house conventional Mark 50 torpedoes or Mark 46 torpedoes and/or special (nuclear) weapons.
