US Navy's new anti-ship missile

US Navy to Re-Fit Tomahawk Cruise Missiles to Attack Ships | The Diplomat - September 14, 2017
Quote
The U.S. Navy has awarded a contract to fit an undetermined number of its long-range Tomahawk cruise missiles with upgraded sensors that will allow the land-strike weapons to target ships. These Maritime Strike Tomahawks will provide a relatively low-cost anti-ship capability as the U.S. Navy works to make up for long-standing gaps in its ability to target adversary fleets, but it’s unclear how they will stack up against other anti-ship cruise missiles (ASCMs) being introduced in the fleet.

The U.S. surface fleet has long led in its ability to provide air defenses over wide areas and launch devastating strikes against targets on land with the existing Tomahawk missile variants, but lags against potential adversaries in being able to sink other ships at long ranges. Russia and China have continued to design and introduce advanced, long-range, and high-speed anti-ship cruise missiles to defeat the sophisticated air defenses on modern warships. The U.S. Navy has long been conspicuous for having only the 1970s-designed Harpoon anti-ship missile to target enemy ships with.

Compared to the most advanced adversary missiles, the Harpoon is slow, un-stealthy, and has a paltry 70 nautical mile range (top-of-the-line adversary missiles are believed to have ranges twice that or more). Compounding those disadvantages in a face-off against a well-armed adversary fleet, only a little over one third of the U.S. destroyers in commission or under construction are even capable of carrying the Harpoon, and the oldest third at that. The rest had no over-the-horizon weapon to engage another warship with until a new high-performance air defense missile, the SM-6, was hastily – by Pentagon procurement standards – modified to be able to engage ship targets.

It's Official, The Navy's Next Anti-Ship Cruise Missile Will Be The Naval Strike Missile

The U.S. Navy has awarded its long-awaited Over-the-Horizon Weapon Systems contract to Raytheon, which had joined together with Norwegian defense contractor Kongsberg to offer the Naval Strike Missile, or NSM. The service sees the weapon as an important anti-ship and land-attack weapon capability for the Littoral Combat Ship and its future frigates, but the selection could also pave the way for adding the missiles to other types of ships and for other services to acquire air- and ground-launched versions.

The Pentagon included the fixed-price deal, valued at more than $14.8 million, in its daily contracting announcement notice for May 31, 2018. The contract has additional options and could be worth nearly $850 million in total. Under the stated terms, the Raytheon-Kongsberg team will supply the weapon systems, consisting of NSMs in canisters, deck-mounted launchers, and a fire control system. In addition, the contract includes funds for mission support and training equipment and other services.

Kongsberg's NSM is a sub-sonic, sea-skimming cruise missile with a range of around 100 miles primarily geared toward taking out enemy ships. The weapon navigates to the general target area using a combination of GPS, inertial navigation system (INS), and terrain recognition, and can either fly over or around islands and other land masses. According to the Norweigan firm, the INS offers an effective backup in the increasingly likely event that an opponent disrupts the GPS connectivity.

In its terminal stage of flight, the missile switches to an infrared imaging seeker to home in on the target. Using a built-in database of representative ship types, the weapon can automatically discriminate between the intended target and other objects, which gives it a high degree of accuracy and makes it much less susceptible to electronic warfare tactics and countermeasures.

The US Navy’s new anti-ship missile scores a hit at RIMPAC, but there’s a twist | Defense news - July 20
Quote
WASHINGTON — The U.S. surface fleet’s brand-new anti-ship missile was used as part of the barrage of rockets and missiles that put an end to the landing ship tank Racine on July 12 during the Rim of the Pacific exercise, but it wasn’t shot by the Navy.

The U.S. Army shot the Naval Strike Missile from the back of a truck using its Palletized Load System in a demonstration that is likely to raise eyebrows in China. The missile, a joint venture between the Norwegian company Kongsberg and Raytheon, was fired from the Pacific Missile Range Facility in Barking Sands, Hawaii, at the former USS Racine, which was floating 55 nautical miles north of Kauai, Hawaii.

Joining the U.S. Army was the Japanese Ground Self-Defense Force, which fired Mitsubishi’s Type 12 surface-to-ship missile.

The Navy inked a contract with Raytheon to start buying the NSM for its littoral combat ships and likely its future frigate. The Army’s shot successfully detonated on target, according to U.S. Pacific Fleet officials.

The shots dovetails with a concept that the Army and the JGSDF have been developing, known in some circles as “archipelagic defense,” which in essence calls for the use of ground forces to deny Chinese forces free movement through the theater by deploying anti-ship and anti-air missiles throughout the island chains that pepper the Asia-Pacific region.
