There are reports coming in of a fatal accident aboard CNSS Warhammer, the singleton test submarine that will help develop the HCS Navy's ballistic missile system SeaGale. An explosion aboard the submarine killed 2 crewmen and blew a hole in the hull. Luckily though for the submarine it was surfaced at the time and close to port. The hole blown in the hull being above the waterline. Warhammer was taken back to port by a tug.
The accident, which has not being confirmed by the HCSN, is now being investigated. The explosion was not related to any SeaGale development work however as this is not set to begin until next year. It is thought an oxygen cylinder exploded, because this design is used on all existing HCSN submarines all submarines currently on patrol have been ordered to surface and hold station until a preliminary investigation can decide if this was a one-off incident or a design flaw in this particular type of equipment.
