Tomahawk

A common designation for the BGM-109, the representative long-range subsonic cruise missile developed by the United States, and a symbolic weapon system of modern precision strike warfare.

Tomahawk

Overview

Tomahawk is a long-range subsonic cruise missile developed by the United States, with the official designation BGM-109 Tomahawk. It can be launched from various platforms, including ground, ship, and submarine, to precisely strike targets thousands of kilometers away, and after being used in large numbers in actual combat during the 1991 Gulf War, it became a symbol of modern precision-guided weapons. It originally began as a strategic cruise missile carrying a nuclear warhead, but after the end of the Cold War, conventional-warhead variants became the mainstay, making it a key means of U.S. military power projection.

Key Details

Development Background

In the 1970s, the United States required a low-altitude cruise missile capable of penetrating the Soviet air defense network. In 1972, General Dynamics (now part of Raytheon) began development, and it was deployed in 1983. It is notable for being designed to enable precise navigation even without GPS by combining TERCOM (Terrain Contour Matching) and DSMAC (Digital Scene Matching Area Correlator).

Specifications and Performance

  • Range: Expanded from about 1,250 km (early variants) to 1,600–2,500 km (improved variants), depending on block
  • Speed: Subsonic (about Mach 0.75)
  • Cruising altitude: Extremely low-altitude penetration at around 30–50 m
  • Propulsion: Turbofan engine + solid-fuel booster
  • Guidance: TERCOM, DSMAC, GPS/INS integrated navigation
  • Warhead: Conventional unitary/penetrator warhead, submunition dispenser type, and initially W80 nuclear warhead

Development by Block

Block I was the initial version, and Block II improved range and warhead performance. Block III applied GPS guidance and an improved warhead, greatly increasing accuracy, while Block IV is a modern version with the ability to retarget and re-attack during flight. The latest Block V strengthens the ability to strike moving maritime targets and can even carry out anti-ship attack missions.

Launch Platforms

Tomahawk has been operated from Aegis destroyers and cruisers equipped with the Mk 41 Vertical Launching System (VLS), Ticonderoga-class cruisers, the vertical launch system of Virginia-class attack submarines, and formerly B-52 bombers. Ground-launched variants resumed development after the termination of the INF Treaty in 2019.

Combat Use

In the 1991 Gulf War, about 288 were launched, neutralizing Iraq's air defense network, and it was used as a key strike asset in Operation Desert Fox in 1998, the Kosovo War in 1999, the Iraq War in 2003, the 2011 Libya operation, and the 2017–2018 Syria strikes. It is a representative example of the "stand-off" concept, in which missiles are launched from outside enemy air defenses to reduce risk to pilots.

South Korea and the Tomahawk

The Republic of Korea Navy has secured the capability to operate Tomahawks on its Aegis destroyers (Sejong the Great class), and based on this, it operates the independently developed long-range cruise missile Hyunmoo-3. The Tomahawk is also frequently mentioned as a reference model for South Korea's Kill Chain system.

Recent Trends

As of 2024–2025, the United States is expanding production centered on Block V and Block Va. Block Va has the ability to strike moving maritime targets and is being deployed to strengthen maritime deterrence in the Indo-Pacific region. In addition, after the termination of the INF Treaty in 2019, Tomahawk was integrated into the ground-launched "Typhon" system, and deployment discussions are underway in places such as Guam and the Philippines. The United States is pursuing a production increase plan to raise annual output from the hundreds to more than 1,000, and discussions on exports and co-production with allies such as Australia and Japan are active. The surge in demand for long-range precision strikes in the war in Ukraine and conflicts in the Middle East is also a factor increasing pressure to expand production. Meanwhile, improvements are being made in parallel to strengthen low-observability and electronic warfare response capabilities in response to Russia and China's upgrading of counter-cruise-missile air defense systems.
