- Streeting said Britain’s nuclear deterrent was not negotiable.
- Maintenance pressures have lengthened submarine patrols.

## Summary

HMS Vengeance returned to the Clyde after a 217-day patrol, described in the article as the longest continuous submerged patrol by a submarine. The homecoming came as Defence Secretary Wes Streeting rejected reported Russian demands that Britain stop protecting Europe with its nuclear deterrent, saying the commitment to Nato allies was not negotiable.

The Vanguard-class submarine has a crew of about 140 and can carry up to 16 Trident missiles. Maintenance pressures have extended patrols from around three months to seven, and Vengeance’s return was delayed when its relief submarine needed spare parts. The article says another Vanguard submarine was already at sea, allowing the crew to come home.
