Mobile Naval Air Base

The Mobile Naval Airfield Organisation (MNAO) was the shore-based component of the naval air logistics organisation. This comprised two types of units, a Mobile Operational Naval Air Base (MONAB) and a Transportable Aircraft Maintenance Yard (TAMY). These were mobile units, the first of which formed in 1944, to provide logistical support to the Fleet Air Arm squadrons of the Royal Navy's British Pacific Fleet, towards the end of World War II.

There were a number of units within and each unit was self-contained and designed to service and repair aircraft and engines. Each were initially assembled at the MNAO Headquarters at HMS Flycatcher, which first commissioned at RNAS Ludham, Norfolk, then later at RNAS Middle Wallop, Hampshire, both in the UK, and then were forward deployed.

When the naval threat in the Atlantic was clearly vanishing, with the decline of Nazi Germany, proposals were made to involve the Royal Navy in the Pacific War. The United States Navy's Commander-in-Chief, Admiral Ernest King, did not welcome this, however. A well-known anglophobe, King preferred to exclude the British and, in addition, he laid down operating requirements that could not be met at the time. One of these was that the Royal Navy should be self-sustaining and independent of United States Navy (USN) logistical resources for extended periods of active service.

King was effectively overruled, and the Royal Navy began establishing an adequate logistical infrastructure which included MONABs.
