The 3M54-1 Kalibr, also known by its NATO reporting name SS-N-27 “Sizzler”, is a high-precision, long-range anti-ship cruise missile developed by NPO Novator (OKB-8). Featuring a two-stage propulsion system with a supersonic terminal phase, the 3M54-1 is designed to penetrate modern naval air defenses and strike high-value maritime targets with devastating effect.
Description and Development
The 3M54-1 Kalibr was tested starting in 2004 and quickly became integrated into the Russian Navy’s surface ships and submarines. Platforms include:
- Buyan-M-class corvettes
- Admiral Grigorovich-class frigates
- Yasen-class, Schuka-B (Akula-class), and Lada-class submarines
Export variants of the missile, such as 3M54E, have been adopted by countries including India, China, Algeria, and Vietnam. India deployed the missile on Sindhughosh-class submarines and Talwar-class frigates, successfully testing it in 2008.
The missile has undergone continuous upgrades to maintain effectiveness against evolving threats, with enhancements to guidance, propulsion, and warhead lethality.

Warhead
The 3M54-1 carries a high-explosive warhead (400–500 kg) optimized to penetrate ship hulls and detonate inside critical systems such as:
- Propulsion
- Weapons systems
- Command and control centers
Its delayed detonation ensures deep penetration, capable of crippling even heavily armored vessels, including destroyers and aircraft carriers.
Design and Propulsion
- Length: 6.2–8.9 m (variant-dependent)
- Diameter: 0.533 m
- Launch weight: 1,300–2,300 kg
- Construction: Lightweight aluminum alloys and composites for durability and aerodynamic efficiency
Propulsion system:
- Launch: Solid rocket booster for stable ascent
- Cruise: Turbojet engine for sustained subsonic speeds (0.8–0.9 Mach)
- Terminal: Secondary booster for supersonic sprint (up to 2.9 Mach), enhancing strike impact and minimizing enemy reaction time
Guidance Systems
The missile integrates multi-mode guidance:
- Mid-course: Inertial Navigation System (INS)
- Long-range: GLONASS satellite navigation
- Terminal: Active radar seeker for precise target acquisition
- Flight profile: Low-altitude sea-skimming reduces radar signature
This ensures effective engagement even in electromagnetically contested environments.
Combat Use
The 3M54-1 Kalibr is deployed from:
- Surface ships (vertical launch systems)
- Submarines (533 mm torpedo tubes)
Its primary mission is neutralizing surface warships, employing stealthy approach and high-speed terminal attack to overcome layered air defenses. The missile can also strike land targets with the 3M-14 variants, making it versatile across maritime and littoral operations.
