Inside the UGHQ (2)

 
Air lock GPO room

This is the entrance to the GPO carrier room. There is an air lock to help reduce the noise from the mechanical frame relays.

GPO VHF room

The GPO VHF room (85 on the plan) looking south. At the top centre is the remains of a 4 light warning lamp. This tunnel and the one to the east of it (86 on the plan) were used during the Cold War up to 1974. After that the high maintenance costs and fire hazards prompted a move of operations to an above ground COMMCEN.

Ratings Heads

Ratings lavatories or "Heads" (99 on the plan). The wooden doorframes seem to have held up well. There is much graffiti (of the Navy kind) dating from the early 1970s  in some of them. A chap called Henwood seems to have been very un-popular with the entire fleet!

Main Chamber 

The main chamber looking south where the Main Operations Room was located (21 on the plan). In 1944 this was the nerve centre for the entire complex. The red linoleum on the floor is probably original as the tunnel was not re-used during the Cold War.

Critall Air Con

The original plans show that the UGHQ was air conditioned, with provision to de-humidify and chill or heat the air. However none of the ducting in this photo is original; it dates from the Cold War era. The manufacturers label on the air ducts is "Crittall Marine" which was not established until 1947. Today the firm is called RMC - Richard Critall Marine.

Construction Sequence

Removal of the inner tunnel lining has revealed the steelwork complete with the original construction sequence numbers.

reinforcement work

At four locations in the UGHQ reinforcement work of the roof was made by the MoD during the 1990s. This was achieved by the building of block walls sealing off a section of tunnel and then pumping concrete into the void. This was puzzlling at first because the expense and effort must have been considerable. However on re-mapping the underground complex the answer was found. Two of the reinforcements are exactly under the west and east wings of the Barrack Block above, and the other two are under the B2177 roadway.
