The targets imitating a group of hostile landing ships were successfully destroyed by Kalibr and Granit cruise missiles at a distance of 200 km. The exercise engaged the Severodvinsk SSGN of Yasen-class project 885 and the Smolensk nuclear submarine of Antey-class project 949A.

The submarines trained joint fire to destroy targets by various cruise missiles with different speed and flight characteristics. Objective controls confirmed successful fire.

About Granit cruise missile

The P-700 Granit is a Soviet and Russian naval anti-ship cruise missile. Its GRAU designation is 3M45, and its NATO reporting name is SS-N-19 Shipwreck. It comes in surface-to-surface and submarine-launched variants, and can also be used against ground targets.

Built by Chelomei/NPO Mashinostroenia, the bulging 10 m missile has swept-back wings and tail, weighs around 7,000 kilograms, and can be fitted with either a 750 kg HE warhead, an FAE warhead, or a 500 kt thermonuclear warhead.

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. The range has been estimated at 400 km, 500 km, and 550–625 km.

The guidance system is mixed-mode, with inertial guidance, terminal active radar homing guidance, and also anti-radar homing. Mid-course correction is probable.
