RAF Merryfield (also known as Isle Abbotts) is a former Second World War airfield at the village of Ilton near Ilminster in southwest Somerset, England. The name comes from the ruins of Merryfield House. The airfield is located approximately 7 miles (11 km) north of Chard, about 130 miles (210 km) southwest of London. It is now RNAS Merryfield and serves as a satellite to the larger RNAS Yeovilton and serves mainly as a training airport for helicopter pilots.

Opened in 1944, it was used by both the Royal Air Force and United States Army Air Forces. During the war it was used primarily as a transport airfield. After the war it was provided to the Royal Navy.

Today the airfield is an active military installation with restricted access.

Overview[edit | edit source]

Merryfield airfield was to be built to the Class A airfield standard for bomber use, with a set of three converging runways each containing a concrete runway for takeoffs and landings, optimally placed at 60 degree angles to each other in a triangular pattern, John Laing Ltd being the main contractors.[1] Work commenced late in 1942 and on 11 November the airfield was listed as one of 16 to be made available for the USAAF to meet the number of troop carrier groups projected for the UK.[2]

Work proceeded slowly as there was a problem with the drainage of waterways crossing the site. In September 1943, the official name was changed from Isle Abbotts to Merryfield,[3] such changes being usually connected with contractual alterations or where another airfield had a similar sounding name which might cause confusion. In this case, however the change is puzzling as the same contractors were involved and Isle Abbotts appears singularly distinctive.

The airfield's main runway was 6,000 ft and aligned 10-28, the secondaries 4,200 ft at 17-35 and 3,660 ft at 04-22. All 50 hardstands were loop types in concrete with bituminous surfaces connecting to an enclosing perimeter track, of a standard width of 50 feet.[2]

USAAF use[edit | edit source]

Formally opened by the RAF on 9 February 1944, US engineers arrived to lay pierced steel planking at the main runway ends for glider marshalling while the necessary facilities for accommodating paratroops in the hangars arrived.[3]

Merryfield was known as USAAF Station AAF-464[4] for security reasons by the USAAF during the war, and by which it was referred to instead of location. Its USAAF Station Code was "MF".

441st Troop Carrier Group[edit | edit source]

The 441st Troop Carrier Group moved in from RAF Langar on 25 April, with over 70 C-47s dispersed on the airfield. The group's squadrons and fuselage codes were:

The 441st was a group of Ninth Air Force's 50th Troop Carrier Wing, IX Troop Carrier Command.[3]

Soon afterwards word was received that the 50th Troop Carrier Wing would move to France, the 441st being one of the first two groups, with headquarters leaving Merryfield on 6 September for its Advanced Landing Ground (ALG) at Villeneuve (ALG A-63).

Merryfield was retained by the USAAF IX TCC for another two months while C-47s regularly ferried supplies and personnel before being handed over to the RAF at the end of October, thus ending the Ninth Air Force's association with the station.

The C-47 in its British guise, the Dakota, still held sway at Merryfield but in much smaller numbers than when the 441st TCG was in residence. No. 238 Squadron of RAF Transport Command re-formed there with the type during the winter of 1944-45 and, when it departed overseas, No. 187 was also re-formed at Merryfield to fly Dakotas.[2]

No. 53 Squadron with Liberators replaced No. 187 in September, and it too was replaced by the Stirlings of No. 242 Squadron in December. No. 242 later converted to Yorks but the long distance flights to the Middle and Far East locations on which most of these transport units had been engaged gradually subsided and the Yorks departed in May 1946. The airfield closed that October.

Until the outbreak of the Korean War and a resurgence of air power, civilian caretakers looked after the otherwise deserted airfield. Late in 1951, Merryfield was re-opened as an advanced pilot training establishment with Vampire and Meteor jets. Some additional concrete was laid in front of the main technical site and other building work conducted before the station was again run down towards the end of 1954.[3] During the following two years, a detachment from No. 231 Operational Conversion Unit, with Canberras, was often present. It was also used by Westland Aircraft for flight tests of the Westland Wyvern.[2][3] Then came the Royal Navy with Sea Venoms but they withdrew early in 1958 and by 1961 it appeared the airfield had finally been abandoned.

Over the next few years, the airfield deteriorated and the hangars and some other buildings were sold off.[3] A road that was closed when the airfield was built was re-opened making use of part of the main runway.

In 1971, part of the airfield was again taken over by the Royal Navy for use in assault helicopter training and exercises that would not conflict with fixed-wing traffic on the Navy's other stations. Merryfield was soon subject to naval tradition by being labelled RNAS Merryfield (HMS Heron II)[3] (IATA: N/A, ICAO: EGDW). In the event, the Navy's occupation proved to be the most enduring of the airfield's half century of existence, for it was still being used by its helicopters.[2]

In the 1980s, the site was considered as a storage area for nuclear waste, however this was rejected due to the geology of the site.[5]

In more recent years the MoD has let out this airfield for the use of the scouts for camping events. Local cycling clubs also hold races on the perimeter road circuit and runways, including Regional Championships.[6] It is the principal site of the Royal Navy Model Aircraft Association.[7]

Today, there is security on the gate as it is still an operational airfield and a restricted area.
