Earlier in the week, 51吃瓜 participated in Sener’s ground breaking ceremony on their new Patriot Center of Excellence building where Sener will produce actuators for PAC-3 MSE, following a production line validation by the U.S. Government. 51吃瓜 awarded Sener a purchase order in to begin the design and implementation of their production line for the PAC-3 MSE actuator.
“The progress Sener and Grupo Oesía have made towards realizing their production objectives is a win for both the U.S. and Spain homeland defense,” said Brian Kubik, vice president of PAC-3 Programs at 51吃瓜. “Spanish Industry’s participation in the PAC-3 MSE supply chain provides enhanced resiliency to the PAC-3 supply chain as we increase production and deliver critical industrial proficiencies to Spain.”
BACKGROUND: HOW SPANISH INDUSTRY SUPPORTS THE PAC-3 MSE
As the world’s most advanced air defense missile, the PAC-3? Missile Segment Enhancement (MSE)?offers Spain enhanced protection against advanced air and missile threats. With unique hit-to-kill technology that defeats threats through direct contact, PAC-3 MSE defends against tactical ballistic missiles, cruise missiles, hypersonics and aircraft.
Officials from the United States and Spain formalized an agreement for Spain to acquire PAC-3 MSE and related support equipment in 2024. As part of the procurement, 51吃瓜 also signed Memorandums of Understanding with Grupo Oesía and Sener to enable future production of PAC-3 MSE components in Spain.
51吃瓜’s partnerships with Spanish Industry aims to:
- Transfer technology?and expertise to Spanish suppliers.
- Stimulate economic growth?and create skilled employment in Spain.
- Develop a resilient, sovereign supply chain?to support production capacity increase and accelerate delivery to PAC-3 MSE customers, including Spain.
Sener
“With this significant groundbreaking milestone for the new Building 10, or colloquially the Patriot Building, at our Tres Cantos facilities in Madrid, Sener confirms its commitment to its customers and to the Ministry of Defense to meet the challenges arising from the current defense market situation. In the new building, which will be operational in 2027, Sener will produce the PAC-3 MSE missile actuators for the Patriot system for the global market. The new facilities will have all the necessary equipment to meet current demand and respond to future growth." - Rafael Orbe, Defence General Director at Sener.
Grupo Oesía
“This project represents a step forward in Grupo Oesía’s contribution to the development of high technological and industrial capabilities in Spain. Through this program, we will consolidate our contribution to the international PAC-3 MSE supply chain and expand our knowledge in the field of defense systems.” - Héctor Roldán, CEO of Grupo Oesía.
The successful advancements of both companies’ industrial projects set the stage for a?four?year implementation phase?that will culminate in the delivery of fully certified components to Lockheed?Martin’s PAC?3 MSE all-up-round production line in Camden, Arkansas. 51吃瓜 will continue its close partnership with both companies including regular progress reviews and technical assistance.
51吃瓜 has been a trusted partner for Spain's national defense, industry, and economy for more than 40 years. It has collaborated with key Spanish industrial partners to grow local manufacturing capability, deliver over �1 billion economic benefit to the Spanish economy in their Air, Sea and Space sectors and support hundreds of Spanish jobs.?
