Introduction: The Rediscovery of High-Intensity Maritime Warfare
Modern naval warfare has entered an era of high intensity where surface warfare is once again the cornerstone of military doctrine. Long focused on asymmetrical projection operations or anti-piracy missions, global navies are facing a resurgence of conventional threats: saturation by subsonic or supersonic anti-ship missiles, kamikaze surface drones, and the reassertion of regional powers.
In this complex tactical landscape, the analysis of surface engagements shows that the effectiveness of a combat ship relies on a fine balance between two complementary dimensions:
- Long-range precision strike and a dissuasive strategic effect, emblematically embodied by the Exocet missile family.
- Close-in self-defense, close-range saturation, and versatile artillery combat, domains ruled by 76mm and 100mm naval guns.
From the foundational test of the 1982 Falklands War to contemporary theaters of operation (Red Sea, Persian Gulf, Indo-Pacific), these weapons have shaped the tactical history of surface fleets and continue to evolve to meet the technological imperatives of the 21st century.
1. The Exocet: The Weapon That Redefined Surface Combat in the Falklands
The Shock of 1982: The Demonstration of Force of a “Ship Killer”
Conceived in the late 1960s and early 1970s by Aérospatiale, the Exocet missile (particularly in its airborne AM39 and surface-to-surface MM38 versions) entered military history on May 4, 1982, during the Falklands War.
That day, a patrol of Argentine Naval Aviation Super-Étendard fighters, guided by discretion and radio silence, launched an AM39 missile against the Royal Navy’s Type 42 destroyer, HMS Sheffield. Flying just above the water (sea-skimming at a mere few meters from the surface) at a subsonic speed of around Mach 0.9, the missile evaded long-range early warning radars before activating its active radar seeker to strike its target’s flank. Although the main explosive warhead did not detonate conventionally upon this specific impact, the fire caused by the propellant’s residual propellants ravaged the vessel, dooming it to burn and eventually sink a few days later.
The psychological and strategic impact was monumental:
- The vulnerability of large ships: A missile of moderate unit cost had just neutralized a state-of-the-art combat vessel, brutally redefining the cost-effectiveness ratio of naval warfare.
- Confirmation of the fire-and-forget concept: The missile’s terminal autonomy proved that a small-scale vector could bypass the constraints of wire-guided or manual guidance systems.
- The sinking of the Atlantic Conveyor: On May 25, 1982, another Exocet struck the logistics cargo ship Atlantic Conveyor, depriving British forces of precious transport helicopters essential for their land advancement.
2. Surface Naval Artillery: The 76mm and 100mm at the Heart of the Fray
While the Exocet dictates the law of destruction at a distance (from 40 to over 200 kilometers depending on the version), close-range combat above the surface inseparably relies on rapid-fire artillery. Two calibers dominate Western and global naval architecture: the 76mm (notably the iconic Otobreda 76mm) and the 100mm (historically developed by France).
The 76mm Gun: Rate of Fire, Agility, and Anti-Missile Versatility
The 76mm gun (especially in its modern Compact, Super Rapid, or Strales versions) has become the de facto standard for NATO and numerous third-party navies on corvettes, frigates, and patrol vessels.
- Blistering rate of fire: With a rate reaching up to 120 rounds per minute in Super Rapid versions, it acts as a true Close-In Weapon System (CIWS) capable of saturating the immediate airspace.
- Smart ammunition: The introduction of guided munitions over time (such as the DART kit or guided shells) allows the 76mm to tackle not only surface targets (fast attack craft, rigid-hull inflatable boats) but also complex, asymmetrical aerial threats, such as sea-skimming anti-ship missiles or drone swarms.
The 100mm Gun: Range, Power, and Surface Supremacy
Massively used by the French Navy (on anti-submarine frigates, La Fayette-class ships, or converted/exported d’Estienne d’Orves-class avisos), the 100mm gun (Mle 68, followed by the high-tech CADAM turret and stealth versions) responds to a slightly different philosophy:
- Impact mass and range: The 100mm shell weighs more and possesses a significantly larger explosive charge than the 76mm. Its effective surface-fire range exceeds 15-17 kilometers.
- Anti-surface and fire support role: It is the ideal tool for warning shots, the neutralization of medium-sized enemy surface vessels, and coastal fire support for special forces or landing troops.
- Automation and stealth: Modern versions integrate composite structures and stealth shapes to minimize the host ship’s radar signature, while being fully automated and remote-controlled from the operations room.
3. The Exocet and Artillery Tested by Modern Conflicts (Iran-Iraq War and Beyond)
The lessons of the Falklands quickly found a dramatic echo in the Persian Gulf during the Iran-Iraq War (1980-1988), often described as the first true modern tanker war.
- Intensive use of the Exocet: Iraqi forces heavily employed Exocet missiles (from Mirage F1 aircraft or modified versions) to disrupt Iranian oil transit. The tragic incident on May 17, 1987, when the US Oliver Hazard Perry-class frigate USS Stark (FFG-31) was struck by two Iraqi Exocets (causing 37 fatalities), brutally recalled the lethality of this weapon and the difficulty alert systems face in countering subsonic sea-skimming vectors.
- The lifesaving role of artillery and countermeasures: During these engagements, onboard guns (76mm and 100mm) regularly served as a last line of defense against asymmetrical coastal threats, while decoy employment doctrines (SRBOC decoy launchers, jammers) underwent radical modernization.
4. 21st-Century Technological Evolution: Modernization and Resilience
Today, in 2026, surface combat doctrine has had to adapt to the digital age, cyberattacks, and the proliferation of asymmetrical swarming threats (autonomous aerial and naval drones).
The Exocet Block 3 and Block 3c: From Pure Surface-to-Surface to Coastal Strike
The Exocet family underwent a major evolution with the development of the MM40 Block 3 and Block 3c versions.
- Turbojet propulsion: Replacing the historical solid-fuel booster, the turbojet (such as the TRI 40) increased the missile’s operational range to over 200 kilometers.
- Littoral capability (Land Attack): Thanks to the integration of GPS guidance and a seeker optimized for discrimination in environments cluttered with islands or civilian traffic, the modern Exocet can strike coastal targets or ships hidden in ports, adapting perfectly to enclosed conflict theaters (such as the Strait of Ormuz or the Red Sea).
Connected Artillery Against Drones
76mm and 100mm guns are no longer mere mechanical metal pieces. They now integrate:
- Hyper-stabilized optronic fire control systems capable of locking onto micro-drones kilometers away, day or night.
- Programmable airburst ammunition, which turns the artillery shell into a destructive wall of steel against multiple aerial threats.
5. Comparative Summary Table of Surface Capabilities
| Weapon System | Type / Primary Role | Range / Caliber | Speed / Rate of Fire | Major Tactical Role |
| Exocet Missile (MM40 Block 3c) | Anti-ship and coastal strike missile | > 200 km | Mach 0.9 (Subsonic sea-skimming) | Destruction of capital ships, long-range maritime interdiction. |
| 76mm Gun (Super Rapid) | Versatile artillery and CIWS | ~15 km (76mm caliber) | Up to 120 rounds/min | Close-in anti-missile/drone self-defense, rapid fire support. |
| 100mm Gun (Mle 68 / Stealth) | Main frigate artillery | > 17 km (100mm caliber) | 60 to 80 rounds/min | Surface combat, destruction of patrol boats, heavy coastal fire support. |
Conclusion: The Inseparable Balance of Surface Power
Surface combat cannot be reduced solely to the brute force of long-range missiles or the sheer agility of close-in artillery. Operational history, from the lightning strikes of Argentine Exocets in the Falklands to the complex engagements of this mid-2020s decade, demonstrates that a modern combat ship must be a balanced platform.
The Exocet ensures strategic ascendancy and long-range interdiction capability, breaking the adversary’s will and offensive capabilities before they even position themselves. In contrast, the 76mm and 100mm guns constitute the ultimate shield and surgical proximity tool, guaranteeing the vessel’s survival against asymmetrical saturation and last-kilometer threats. Control of the seas depends, today as yesterday, on this absolute complementarity.
