British military aircraft designation systems
Encyclopedia
British military aircraft designations are used to refer to aircraft
types and variants operated by the armed forces of the United Kingdom
.
Since the end of the First World War, aircraft
types in British
military service have generally been known by a name (e.g. "Spitfire"), with individual variants recognised by mark numbers, in contrast to the systems such as that used in the United States
, where an aircraft type is primarily identified by an alphanumeric designation.
The British military aircraft designations (e.g. "Spitfire Mark V" or "Hercules C3") should not be confused with the serial number
used to identify individual aircraft (e.g. "XR220"), nor with U.S. aircraft designations (e.g. "C-5", "C-17", "MQ-9") or manufacturer's designations (e.g. "S-58", "Jaguar B", "WS-61
", "AW139
", "WAH-64", "Lynx Mk.21A
").
No designation system was introduced during World War I that covered more than the products of a single manufacturer. The Admiralty
frequently referred to designs by the serial of the first aircraft of that type to be accepted for service.
or Admiralty
and the manufacturer/importer when the order was placed. Names generally followed one or a number of patterns:
The systems began to change in the immediate post-Second World War period with the V bombers and types such as the Supermarine Scimitar
. The RAF's three post-war jet-engined
, swept wing
strategic bombers were given names beginning with "V" - Vickers Valiant
, Avro Vulcan
and Handley Page Victor
(the V Bombers).
, variants of each operational type were usually indicated by a mark number
, a Roman numeral added to the type name, usually preceded by "Mark", "Mk." or "Mk" (e.g. Fury Mk I). Mark numbers were allocated sequentially to each new variant, the new mark number signifying a 'major' change such as a new engine-type. Sometimes an alphabetic suffix was added to the mark number to indicate a minor change (e.g. Bulldog Mk IIA). Occasionally, this letter indicated a change in role, e.g. the Blenheim Mk I bomber was adapted to the Blenheim Mk IF long-range fighter.
During the Second World War, as aircraft ordered for one purpose became adapted to a multitude of roles, mark numbers became prefixed with letters to indicate the role of that variant. Aircraft of the same mark that were adapted for different purpose would then be differentiated by the prefix. For instance the Defiant Mk I was adapted to a night fighter
, the Defiant NF Mk II, some of which were later converted to target tug
s as the Defiant TT Mk II. Where there was a Sea- variant, this would have its own series of mark numbers (e.g. the Seafire Mk I was derived from the Spitfire Mk V).
Occasionally other 'minor' but nonetheless important changes might be denoted by series numbers, preceded by "Series", "Srs." or "Srs" (e.g. Mosquito B Mk IV Series I / B Mk IV Series II - the different series number denoting the introduction, after a few initial production aircraft, of extended engine nacelles to eliminate buffeting. This design change was made standard on all subsequent production Mosquitoes). The series number denoted a revision during the production run of a particular Mark. This again could then have an additional letter-suffix (e.g. the Halifax Mk II Series IA).
Export variants of British military aircraft are usually allocated mark numbers (sometimes without a role prefix) from a higher range of numbers, usually starting at Mark 50. A converse convention was adopted for the Canadian-designed de Havilland Canada DHC-1 Chipmunk
, where the sole British service variant was designated Chipmunk T.10.
Up until the end of 1942, the RAF always used Roman numerals for mark numbers. 1943-1948 was a transition period during which new aircraft entering service were given Arabic numerals for mark numbers but older aircraft retained their Roman numerals. From 1948 onwards, Arabic numerals were used exclusively. Thus, the Spitfire PR Mk XIX became the PR Mk 19 after 1948. With this change, the Sea- variants were allocated their own range within one common series for all variants (e.g. the Hawker Fury Mk I was followed by the Sea Fury F.10, Sea Fury FB.11 etc).
For example, the first Lockheed Hercules variant in RAF service was the Hercules C.1 ("Cargo, Mark 1"). A single example was adapted for weather monitoring purposes and became the Hercules W.2. The stretched variant became the Hercules C.3. With aircraft with a long service life, as their function changes over time, the designation letters and sometimes the mark digit will change to reflect this.
The post-1948 mark numbers are variously presented in full (e.g. Hercules C Mk 3) or abbreviated (e.g. Hercules C3) forms, and either with or without a full stop
between the prefix and mark number. The use of the "Mark" or "Mk." has gradually been dropped.
aircraft would be produced under contract and would be referred to as by Manufacturer Name and Specification Number. If accepted they would get a service name. For example, the Fairey 6/22; this being the 6th specification issued in the year 1922 that was accepted as the Fairey Flycatcher
. Later, a preceding letter was added to the Specification Number to identify the type of aircraft; e.g. the Bristol B.28/35, a bomber aircraft, the 28th specification of the year 1935, which would become the Bristol Blenheim
.
's Royal Flying Corps
was the Royal Aircraft Factory. The Royal Aircraft Factory designated its types according to either the layout of the aircraft or its role - e.g. Royal Aircraft Factory S.E.5
, the "S.E." prefix representing Scouting Experimental.

An aircraft is a vehicle that is able to fly by gaining support from the air, or, in general, the atmosphere of a planet. An aircraft counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines.Although...

Mark numbers
Starting in the interwar periodInterwar period
Interwar period can refer to any period between two wars. The Interbellum is understood to be the period between the end of the Great War or First World War and the beginning of the Second World War in Europe....
, variants of each operational type were usually indicated by a mark number
Mark (designation)
The word Mark, followed by number, is a method of specifically designating a standardized, integrated, assumed to be functional and unique version of a mechanical and/or electrical hardware product that has completed the design process and has been approved to be put into final production, as well...
, a Roman numeral added to the type name, usually preceded by "Mark", "Mk." or "Mk" (e.g. Fury Mk I). Mark numbers were allocated sequentially to each new variant, the new mark number signifying a 'major' change such as a new engine-type. Sometimes an alphabetic suffix was added to the mark number to indicate a minor change (e.g. Bulldog Mk IIA). Occasionally, this letter indicated a change in role, e.g. the Blenheim Mk I bomber was adapted to the Blenheim Mk IF long-range fighter.
During the Second World War, as aircraft ordered for one purpose became adapted to a multitude of roles, mark numbers became prefixed with letters to indicate the role of that variant. Aircraft of the same mark that were adapted for different purpose would then be differentiated by the prefix. For instance the Defiant Mk I was adapted to a night fighter

, the Defiant NF Mk II, some of which were later converted to target tug

s as the Defiant TT Mk II. Where there was a Sea- variant, this would have its own series of mark numbers (e.g. the Seafire Mk I was derived from the Spitfire Mk V).
Occasionally other 'minor' but nonetheless important changes might be denoted by series numbers, preceded by "Series", "Srs." or "Srs" (e.g. Mosquito B Mk IV Series I / B Mk IV Series II - the different series number denoting the introduction, after a few initial production aircraft, of extended engine nacelles to eliminate buffeting. This design change was made standard on all subsequent production Mosquitoes). The series number denoted a revision during the production run of a particular Mark. This again could then have an additional letter-suffix (e.g. the Halifax Mk II Series IA).
Export variants of British military aircraft are usually allocated mark numbers (sometimes without a role prefix) from a higher range of numbers, usually starting at Mark 50. A converse convention was adopted for the Canadian-designed de Havilland Canada DHC-1 Chipmunk
De Havilland Canada DHC-1 Chipmunk
The de Havilland Canada DHC-1 Chipmunk is a tandem, two-seat, single-engined primary trainer aircraft which was the standard primary trainer for the Royal Canadian Air Force, Royal Air Force and several other air forces through much of the post-Second World War years...
, where the sole British service variant was designated Chipmunk T.10.
Up until the end of 1942, the RAF always used Roman numerals for mark numbers. 1943-1948 was a transition period during which new aircraft entering service were given Arabic numerals for mark numbers but older aircraft retained their Roman numerals. From 1948 onwards, Arabic numerals were used exclusively. Thus, the Spitfire PR Mk XIX became the PR Mk 19 after 1948. With this change, the Sea- variants were allocated their own range within one common series for all variants (e.g. the Hawker Fury Mk I was followed by the Sea Fury F.10, Sea Fury FB.11 etc).
Format of designation
The system has been largely unchanged since 1948 with the addition of more prefixes as new roles have arisen.For example, the first Lockheed Hercules variant in RAF service was the Hercules C.1 ("Cargo, Mark 1"). A single example was adapted for weather monitoring purposes and became the Hercules W.2. The stretched variant became the Hercules C.3. With aircraft with a long service life, as their function changes over time, the designation letters and sometimes the mark digit will change to reflect this.
The post-1948 mark numbers are variously presented in full (e.g. Hercules C Mk 3) or abbreviated (e.g. Hercules C3) forms, and either with or without a full stop
Full stop
A full stop is the punctuation mark commonly placed at the end of sentences. In American English, the term used for this punctuation is period. In the 21st century, it is often also called a dot by young people...
between the prefix and mark number. The use of the "Mark" or "Mk." has gradually been dropped.
Specification numbers
From 1920 to 1949, most aircraft had an associated Air Ministry specification number. PrototypePrototype
A prototype is an early sample or model built to test a concept or process or to act as a thing to be replicated or learned from.The word prototype derives from the Greek πρωτότυπον , "primitive form", neutral of πρωτότυπος , "original, primitive", from πρῶτος , "first" and τύπος ,...
aircraft would be produced under contract and would be referred to as by Manufacturer Name and Specification Number. If accepted they would get a service name. For example, the Fairey 6/22; this being the 6th specification issued in the year 1922 that was accepted as the Fairey Flycatcher
