The missiles were launched at dawn on Sunday and flew for more than two hours, covering a distance of 932 miles, according to the North’s state-run Korean Central News Agency. The report said they were fired from the 8.24 Yongung, the only submarine capable of launching missiles that North Korea is known to possess. The latest version of the submarine has the new Virginia Payload Module; in addition to the basic 12 cruise missile launch tubes, the VPM caries and launches up to 28 additional cruise missiles.

State media photographs published on Monday showed a missile launching into a cloudy sky from the water trailed by a plume of smoke which obscures the type of platform it was being fired from. While the specification of the missile is yet to be precisely known, the prefix “strategic” implies that it can eventually be equipped with a nuclear warhead. The SLCM-N was recommended early in 2018, but it took several years for officials to complete the military requirements and conduct an analysis of alternatives. By this point, there was a new administration, and the Biden administration’s Nuclear Posture Review (NPR) reversed the SLCM-N decision in 2022. While there was no disagreement over the regional nuclear threat or the need to counter adversary limited nuclear use, the Biden NPR concluded that the threat could be handled with existing—and soon to be modernized—nuclear forces, thereby avoiding the costs of a new program.
History of development
Raytheon was contracted to integrate the upgraded navigation and communication systems into the Block IV Tactical Tomahawk (TACTOM) missile in March 2020. State news agency KCNA and official Rodong Sinmun newspaper said on Jan 29 the missiles flew above the sea off the country’s east coast for 7,421 seconds and 7,445 seconds and hit an unspecified island target, indicating the flight time exceeded two hours. In recent months, the North has tested an array of weapons that include ballistic missile systems that are under development and an underwater drone.

Navy and United Kingdom Maritime Trade Operations (UKMTO) to issue warnings of potential shipping attacks on April 5-6. The warnings were especially geared toward Israeli cargo ships and tankers, which were reportedly asked to navigate away from Iranian waters with their transponders turned off. Since February 2021, the IRGC has attacked Israeli-linked commercial vessels in the Gulf of Oman or Arabian Sea at least seven times, using suicide drones and/or limpet mines to damage the ships and, in one case, kill crewmembers. Meanwhile, rising tensions in the West Bank led to multiple rocket strikes against Israel, some launched by Palestinian factions in south Lebanon and others from Gaza and Syria. The risk of escalation is significant given ongoing tensions at the Temple Mount/al-Haram al-Sharif and Iran’s declared “Qods (Jerusalem) Day,” which falls today, the last Friday of Ramadan. In this environment, the United States and its partners can benefit from the USS Florida’s deterrent effect and robust intelligence collection capabilities—and, if necessary, from its additional firepower.
Guidance and control
NCM provides a unique operational capability, with very long range high-precision strike against politically/military sensitive targets. The missile has been designed for vertical launch from the compact A70 SYLVER vertical launcher which is also capable of housing other MBDA missiles such as the ASTER family of air defence missiles. NCM has also been designed to be launched from the 21 inch torpedo tubes of a submerged submarine. Conventionally armed BGM-109 Tomahawk cruise missiles are the mainstay of the Navy’s arsenal for attacking land targets.

The report came a day after South Korea’s military said it detected North Korea firing multiple cruise missiles over waters near the eastern port of Sinpo, where the North has a major shipyard developing submarines. It was the latest in a streak of weapons demonstrations by North Korea amid increasing tensions with the United States, South Korea and Japan. North Korea said on Monday that it had fired two strategic cruise missiles from a submarine, its first such missile test, as South Korea and the United States were about to begin a major joint military exercise. “Arming such vessels with nuclear cruise missiles would also reduce the number of conventional missiles each boat could carry, at a time when Pentagon leaders argue that strengthening conventional deterrence is their top priority in the Asia-Pacific,” says Reif. In 1947, the United States launched a JB-2 Loon, a direct copy of the German V-1, was launched from the deck of the submarine USS Cusk. This test proved it could be done, but the Cusk used an unpolished, jerry-rigged system.

A submarine-launched cruise missile (SLCM) is a cruise missile that is launched from a submarine (especially a SSG or SSGN). Current versions are typically standoff weapons known as land-attack cruise missiles (LACMs), which are used to attack predetermined land targets with conventional or nuclear payloads. Anti-ship cruise missiles (ASCMs) are also used, and some submarine-launched cruise missiles have variants for both functions. The Soviet Navy converted 13 Whiskey-class submarines (Project 613) for the land-attack cruise missile (LACM) role in the late 1950s (Whiskey Single Cylinder, Whiskey Twin Cylinder, Whiskey Long Bin), armed with the SS-N-3 Shaddock (П-5) missile. The Navy’s four converted Ohio-class SSGNs are usually tasked with highly secretive intelligence gathering and conventional strike missions. They are armed with up to 154 vertically launched precision-guided TLAM-E Tomahawk cruise missiles (UGM-109E Block IV) with a range of up to 1,600 km and a 454 kg warhead.
Successfully launched by the USS George Washington, this missile was a revolutionary development because it allowed a boomer, another name for a ballistic missile submarine, to remain submerged. Subsequent missiles have all been refinements of the same basic design, invisible and unstoppable. Submarines couldn't always launch airborne missiles from under the sea, of course. During both World Wars, submarines were armed with torpedoes and deck-mounted guns—heavy cannons for engaging surface ships and lighter anti-aircraft weapons. Mine-laying submarines also terrorized the sea in the first half of the 20th century.

On Jan 29, it said the claimed flight time was an exaggeration, saying it tracked the missiles in real time and also played down the possibility that it was propelled by solid fuel. South Korea's military said on Sunday that the North fired multiple cruise missiles off its coast but did not provide details. On Monday, it said the claimed flight time was an exaggeration saying it tracked the missiles real time and also played down the possibility it was propelled by solid fuel. The historic test took place yesterday (18 April 2024) and involved first ship-in-class Aquitaine (D650) and a Suffren-class nuclear powered submarine (SSN). The frigate was located off Britany while the SSN was cruising in the Bay of Biscay. The two naval cruise missiles simultaneously hit a target located at the DGA’s missile test center South of Bordeaux.
Decades later, the ballistic missile submarine is still considered the most secure leg of the nuclear triad (land-, air-, and sea-launched nukes). The original Polaris had a range of about a thousand miles and delivered a single 600-kiloton warhead with an accuracy of around a mile. In 1972 a new version entered service (originally known as the Polaris B3 but then renamed Poseidon C3) with had a range of almost 3,000 miles, and carried up to twelve warheads. In 1979 came the sea god's most trusted weapon—the Trident C4, which carried the same payload to a distance of 4,600 miles.
Raytheon planned to undertake recertification and modernisation programmes for Tomahawk Block IV missile in 2019 to add maritime strike capability and multiple-effects warhead upgrades to the missiles. The 4,000th Tomahawk Block IV missile was delivered to the US Navy in August 2017. The US Navy warships and submarines launched 66 GPS-enabled Tomahawk missiles at Syrian chemical weapon facilities in 2018. The US Navy placed a $338m contract with Raytheon in June 2012 for the delivery of 361 Tomahawk Block IV tactical cruise missiles. Another contract worth $254.6m was awarded for Tomahawk Block IV in the same year. The Tactical Tomahawk Weapons Control System (TTWCS) integrated within the ship’s systems computes the path to engage targets.
TTWCS is also used to communicate with multiple missiles for reassigning the targets and redirecting the missiles in flight. The Tomahawk Land Attack Missile (TLAM) can strike high-value or heavily defended land targets. North Korea has an estimated 70 to 90 diesel-powered submarines in one of the world’s largest submarine fleets. Biden himself noted that fielding low-yield weapons as alternatives to more powerful ballistic missiles would make the U.S. “more inclined to use them” and increase the risk of a nuclear war.
