Exocet is a family of French anti-ship missiles developed for ships, aircraft, coastal batteries and submarines. Its combat record made the name familiar, but the MM38, AM39, SM39 and successive MM40 blocks should not be treated as one identical weapon. Launch platform, seeker and mission planning determine the engagement envelope.
Versions and guidance
The early MM38 established a ship-launched sea-skimming missile; AM39 serves aircraft and SM39 submarines. The later MM40 series introduced substantial changes. MBDA’s MM40 Block 3C description highlights programmable three-dimensional waypoints, optimised trajectories and coordinated terminal attacks. These are manufacturer specifications for that version, not characteristics of every Exocet in service.
An anti-ship missile normally uses navigation to approach a target area and its own seeker for the final phase. Low flight over the sea reduces the horizon at which a ship can detect it, but does not make it invisible. Targeting quality, electronic countermeasures, shipboard sensors and crew readiness all shape an engagement. A published maximum range says little without a reliable track and an appropriate launch position.
The Falklands lesson and modern use
Argentine AM39 Exocets struck British ships in 1982, most famously HMS Sheffield and Atlantic Conveyor. Those attacks demonstrated the importance of sea-skimming weapons and naval warning, but the outcomes cannot be reduced to a single missile specification. Aircraft, reconnaissance, rules of engagement and damage control all mattered. The Falklands air campaign provides the wider operational context.
For a navy, Exocet remains a stand-off strike option only when sensors and command systems can provide timely target data. Later variants offer more flexible routing and seekers, while defenders have also improved surveillance, soft-kill measures and point defence. A sound assessment compares a particular Exocet block against a particular target and defensive network.
