Westwire Harnessing has opened a second UK manufacturing facility in Swindon, expanding its production footprint and creating around 80 new skilled jobs. The new site doubles the company’s UK floor space, increasing capacity from 10,000 to over 21,000 square feet. The company claims the new facility will triple its defence output in the UK.
“Today marks an important milestone for Westwire,” said Managing Director, Andy Russell. “The opening of our new Swindon facility significantly enhances our manufacturing capability and underlines our commitment to delivering innovative, high-quality solutions that support our armed forces.”
Westwire Harnessing designs and manufactures electrical wiring interconnect systems and electronic integrated systems used in military aircraft, drones, land platforms, and critical national infrastructure. Its products are built to operate in harsh environments.
The expansion follows a period of rapid growth. Since 2021, Westwire’s revenue has increased almost fourfold, reflecting increased procurement activity across the UK defence and aerospace market. The Swindon facility enables higher throughput while maintaining the hand-built production approach required for complex and safety-critical harnesses.
Westwire operates as part of SASMOS HET Technologies, which acquired the business in 2021 in its first investment outside India. The parent group provides access to complementary capabilities including fiber optics, photonics, and power management, as well as technology transfer that supports the UK operation’s expansion without shifting production offshore.
“Westwire is an important part of Swindon’s industrial fabric,” said local MP Will Stone. “The creation of 80 high-quality jobs is fantastic news for our community and reflects the town’s growing role in advanced manufacturing and the UK defence sector.”
