## Key points

- HMS Vengeance completed a record 217-day submerged patrol.
- The previous submarine patrol record was 205 days.
- Maintenance delays are extending missions and raising crew welfare concerns.

## Summary

HMS Vengeance has returned to Faslane after spending a record 217 days submerged on patrol, 12 days longer than the previous record. The deployment has renewed concerns about the ageing submarine fleet’s maintenance delays and the effects of increasingly long missions on sailors.

The Vanguard-class boats were designed for three to four months at sea, carrying food for crews of about 140, and cannot be resupplied while their locations remain secret. The Royal Navy’s chief says maintenance needs to improve so submarines can return to service faster. The article also describes concerns about crew welfare and past allegations of bullying and abuse in the submarine service.
