Lockheed Martin Tests PAC-3 MSE Interceptor, Neutralizing Mock Cruise Missile

Neva: Lockheed Martin has successfully test-fired a Patriot PAC-3 MSE interceptor from a Mk 41 Vertical Launch System (VLS)-derived containerized launcher, intercepting a mock cruise missile. This innovative combination provides an ditional air and missile defence option for existing and future launchers, both on ships and land. This capability could dress growing concerns within U.S. Navy about maintaining a stey supply of surface-to-air and or missiles during potential high-end conflicts, such as one in Pacific against China.  

recent test involved a Mk-41-derived four-cell Mk 70-series containerized launcher, according to a press release from Lockheed Martin. A modular and scalable version of Aegis Combat System called Virtualized Aegis Weapon System, was used to execute launch. This system, like its parent, can network with various weapon systems and sensors. Lockheed Martin conducted test in partnership with multiple Department of Defense Services and Components, though specific partners were not named.  

New Test Highlights Versatility and Tactical vantages  

test demonstrated PAC-3 MSE’s ability to be cued by an AN/SPY-1-series rar using Aegis, following a validation last June. In U.S. Navy, AN/SPY-1 rar variants are primary sensors linked to Aegis Combat Systems on Ticonderoga-class cruisers and most Arleigh Burke-class destroyers. PAC-3 MSE uses initial cueing to navigate to a target’s projected path using an inertial navigation system, with mid-course guidance updates provided via datalink. Upon reaching target location, interceptor’s active rar seeker engages target, aiming for a hit-to-kill impact.

PAC-3 MSE, with its small explosive warhe, ejects metal fragments to increase interception probability against smaller targets like cruise missiles or aircraft. This missile can also engage ballistic missiles during ir terminal flight stages. U.S. military views cruise missiles as a significant threat, with vanced air, sea, and ground-launched variants developed by near-peer competitors like China and Russia.  

apting to Modern Threats with vanced Missile Technology  

Firing PAC-3 MSEs from any Mk-41-based launch system is a significant development. This includes BAE Systems' modular aptable Deck Launching System, an angled deck-mounted launcher for ships. Lockheed Martin notes that PAC-3 MSE is compact enough for tactical-length Mk 41 versions, expanding potential platform integration. Virtualized Aegis system furr enhances operational flexibility.

Lockheed Martin’s successful test represents a significant vancement in missile defence technology, offering enhanced protection and strategic flexibility for U.S. military and its allies. integration of PAC-3 MSE interceptors with Mk 41 launch systems exemplifies ongoing evolution of defence capabilities in response to modern threats.  

Potential Implications for U.S. Military and Allied Forces  

U.S. Marine Corps plans to field a ground-based Tomahawk capability using a single-cell Mk 41-based launcher on an uncrewed Joint Light Tactical Vehicle (JLTV) derivative. PAC-3 MSE/Mk 41 combination offers logistical benefits, complementing existing missile options like SM-6. SM-6, primarily a surface-to-air missile, also engages ballistic and hypersonic threats and can target ships and surface entities.

U.S. Army's ground-based Typhon missile launch system, utilizing Mk 41-based launchers and an Aegis-derived fire control architecture, is designed to fire SM-6s and Tomahawk cruise missiles. Integrating PAC-3 MSEs into Typhon could bolster Army's air and missile defence capabilities, dressing high demand and limited size of Patriot force. This integration highlights potential for a versatile and resilient defence infrastructure, capable of apting to evolving threats.
