The P-700 Granit (Russian: П-700 "Гранит"; English: granite) is a Soviet and Russian naval anti-ship cruise missile. Its GRAU designation is 3M45, its NATO reporting name SS-N-19 Shipwreck. It comes in ASCM and SLCM variants.

The P-700 was designed in the 1970s to replace the P-70 Ametist and P-120 Malakhit, both effective missiles but with too short a range in the face of improving weapons of U.S. Navy carrier battle groups. The missile was partially derived from the P-500 Bazalt.
Built by Chelomei/NPO Mashinostroenia, the bulging 10m missile has swept-back wings and tail, weighs around 7,000 kilograms and can be fitted with either a 750 kg HE warhead, a FAE warhead, or a 500 kt nuclear warhead. A stubby cylindrical solid-fuel rocket is fitted to the rear for launch; this booster stage is released when the missile enters sustained flight using its KR-93 turbojet engine. The P-700 has a distinctive annular air intake in the nose. Maximum speed is believed to be between Mach 1.6 and Mach 2.5. Range is estimated at 550 to 625 km.[1] The guidance system is mixed-mode, with inertial, active terminal guidance with radar and also anti-radar homing. Mid-course correction is probable.
The missile, when fired in a swarm (group of 4-8) has a unique guidance mode. One of the weapons climbs to a higher altitude and designates targets while the others attack. The missile responsible for target designation climbs in short pop-ups, so as to be harder to intercept. The missiles are linked by data connections, forming a network. If the designating missile is destroyed the next missile will rise to assume its purpose. Missiles are able to differentiate targets, detect groups and prioritize targets automatically using information gathered during flight and types of ships and battle formations pre-programmed in an onboard computer. They will attack targets in order of priority, highest to lowest: after destroying the first target, any remaining missiles will attack the next prioritized target.[2][3]
The P-700 was derived from the P-500 Bazalt, substituting the earlier missile's solid-fuel propulsion for a turbojet. The P-700 was in turn developed into the P-800 Oniks, which uses ramjet propulsion, and the BrahMos missile, a joint-Indian/Russian modernization of the P-800.
Initial deployment was aboard the cruiser Kirov (now the Admiral Ushakov) in 1980. It is currently in service with the Russian Northern Fleet on the Kirov-class battlecruisers Admiral Nakhimov and Pyotr Velikhy, the aviation cruiser Kuznetsov and as part of the larger guided missile submarines armoury (the Kursk carried 24 missiles). However, the size of the missile limits the platforms on which it can operate and be launched from .
