P-700 Granit

P-700 Granit. The P-700 Granit is a long-range, supersonic heavyweight Anti-ship missile developed by the Soviet Union during the Cold War. Designed to defeat U.S. Navy carrier battle groups, it entered service with the Soviet Navy in 1983 and remains a key component of the Russian Navy's anti-ship arsenal. The missile is renowned for its high speed, large warhead, and sophisticated swarm intelligence capabilities.

Development and design

The development of the P-700 was initiated by the Chelomey Design Bureau, later known as NPO Mashinostroyeniya, in the early 1970s as a successor to the P-70 Ametist and P-120 Malakhit missiles. The program aimed to create a weapon system that could autonomously coordinate attacks in large salvos, overwhelming enemy fleet defenses. Key design features included a powerful KR-21 turbojet engine, enabling sustained supersonic flight, and a sophisticated guidance suite. This suite combined an inertial navigation system for the cruise phase with terminal active radar homing, and was notably augmented by a unique data-link system. This system allowed missiles in a salvo to share target data, with one missile climbing to act as a scout while others flew low, creating a highly resilient and intelligent attack pattern intended to penetrate the AEGIS defense network of Nimitz-class carriers.

Operational history

The P-700 Granit entered operational service in 1983, primarily arming the Project 949 *Oscar*-class nuclear-powered cruise missile submarines and the *Kirov*-class battlecruisers, including the *Pyotr Velikiy*. During the Cold War, these platforms formed a central pillar of Soviet anti-access/area denial (A2/AD) strategy against NATO naval forces in the Atlantic Ocean and Mediterranean Sea. The missile system saw no combat use during the Soviet era but has been maintained as a strategic deterrent by the Russian Armed Forces. In the 21st century, the Granit-equipped *Oscar*-class submarines and the *Admiral Nakhimov* have remained active in exercises, projecting power in regions like the North Atlantic and the Arctic Ocean, underscoring Russia's continued reliance on the system for sea denial.

Technical specifications

The P-700 is a large missile, measuring 10 meters in length, 0.85 meters in diameter, and weighing approximately 7,000 kilograms. It is propelled by a four-chamber KR-21 turbojet engine with a solid-fuel booster, achieving a maximum speed in excess of Mach 2.5 at high altitude. Its operational range is officially stated as 625 kilometers. The missile can be armed with either a 750-kilogram high-explosive semi-armor-piercing warhead or a nuclear warhead with an estimated yield of 500 kilotons. Its guidance system is a multi-mode hybrid, using inertial guidance mid-course, terminal active radar homing, and supplemented by the proprietary data-link for in-flight target coordination and re-targeting.

Variants and upgrades

The primary variant is the basic P-700, also known by its NATO reporting name SS-N-19 Shipwreck. While the core design has seen few major alterations, there have been ongoing programs to modernize its electronics and guidance systems to maintain effectiveness against evolving naval air defenses. Proposals for a successor, such as the 3M22 *Zircon* hypersonic missile, have been developed, but the Granit remains in active service. Upgrades have likely focused on improving compatibility with modern Russian command and control networks, such as those integrated on the *Yasen*-class submarines, and refining its countermeasures against systems like the SM-3 and SM-6.

Operators

The sole operator of the P-700 Granit is the Russian Navy, which inherited all assets from the Soviet Navy. The missile is deployed exclusively aboard specific capital ships: the *Oscar*-class (Project 949A) submarines, such as the *Smolensk*, and the *Kirov*-class (Project 1144) battlecruisers, notably the *Pyotr Velikiy* and the modernizing *Admiral Nakhimov*. No exports of this strategic weapon system have been made, and it is not known to be in service with any other navy, including the PLA Navy of China.
