Overview
- HII added about 6,500 square feet at Portchester, doubling the site to serve as its principal European hub, with phased full use targeted by Q3 2026.
- The facility will sustain and train REMUS users, perform REMUS 620 assembly-level work and service launch-and-recovery systems, keeping more maintenance in Europe.
- HII recently demonstrated automated shipboard launch and recovery of a REMUS UUV using its Sea Launcher system, advancing manned–unmanned integration.
- Portchester is being readied to support the ROMULUS USV family, with the lead ROMULUS 190 under construction and sea trials planned in 2026.
- The site underpins HII’s MoU with Babcock on torpedo‑tube launch and recovery for submarines, and the workforce is set to grow by roughly 8–10 roles from a base of seven.
