During the First World War the RNAS had structured its force to protect Britain from both surface sea and air attack. Against surface attack the RNAS had built up a force of seaplanes and in support of these had accumulated between 300 and 500 vessels<ref name=RAFASRS1918-1986 /> of various kind including [[Pinnace (ship's boat)|pinnaces]], lighters, [[launch (boat)|launches]], motorboats, [[depot ship]]s and other vessels. These were used as primarily as [[seaplane tender]]s. The term seaplane tender in British usage being used for small watercraft of launch to pinnace size used as [[Ship's tender|tenders]], what in United States usage would be called a seaplane tender the British would call a seaplane depot ship. These craft were used to ferry crews, stores and supplies between shore and the aircraft, to maintain the buoys used to mark out "taxiways" and "runways" and to keep these clear of debris to prevent [[foreign object damage]], and in the case of emergency to act as rescue craft and [[airport crash tender]]s.<ref name=RAFASRS1918-1986 /> All those functions that on land would require wheeled [[ground support equipment]] had a need for a watercraft equivalent. Other vessels were equipped as high speed [[target tug]]s, pickets and for range safety. On the creation of the RAF, along with the seaplanes they served, these RNAS vessels and their crews would become the RAF's Marine Craft Section (MCS),<ref name=RAFASRS1918-1986 /> However, the Navy was from the start opposed to and did its best to prevent the creation of the new service, of the vessels that were now theoretically part of the RAF some could not be found; others were carried aboard Royal Navy vessels that were not part of the RNAS transfer, and to which the RAF had no option but to accede to their transfer back to the Navy. The MCS officers tasked with carrying out an inventory of the new service's assets concluded that achieving the transfer of 323 vessels was possible. However, of those boats handed over, because of their war service, some 50% were unserviceable, with some in such a poor state of repair as to be totally unseaworthy. ===Interwar=== In the [[interwar period]] the MCS contracted to a force of 150 vessels, which in addition to supporting the operation of seaplanes were equipped for rescue operations, with a launch being at the ready whenever an aircraft was flying over water.<ref name=RAFASRS1918-1986 /> However, the training and seamanship of the crews, especially with regards to navigation, and the fact that these boats were hard pressed to make {{convert|10|kn|mph km/h|abbr=on}}, meant that the MCS at this time was only capable of inshore rescue operations.<ref name=RAFASRS1918-1986 /> The MCS were subdivided into Marine Craft Units (MCU) with individual units assigned to an individual [[RAF Coastal Command]] [[List of seaplane bases in the United Kingdom|seaplane base]]. In 1921 the RAF was officially granted its own [[Ensign (flag)|ensign]], to the dissatisfaction of the Navy, and henceforth MCS vessels would fly the [[Royal Air Force Ensign]]. As the vessels it had inherited from the Navy began wear out the MCS began to have built for it launches capable of higher speeds and - in light of the larger crews of some aircraft - greater capacity. The arrival of high speed craft into the MCS was driven in part by [[T.E. Lawrence]], better known as "Lawrence of Arabia", whilst an airman at [[RAF Mount Batten]]; Lawrence had previously witnessed the drowning of the crew of a seaplane when the seaplane tender sent to their rescue was too slow in arriving. Working with [[Hubert Scott-Paine]], the designer of the record-breaking ''[[Miss Britain III]]'' and [[Miss England (speedboat)|''Miss England'']] boats and founder of the [[British Power Boat Company]] (BPBC), the {{convert|37.5|ft|m|1|abbr=on}} long ST 200 Seaplane Tender Mk1 was introduced into service. These boats had a range of {{convert|140 |mi|abbr=on}} when cruising at {{convert|24|kn|mph km/h|abbr=on}}, and could achieve a top speed of {{convert|29|kn|mph km/h|abbr=on}}. As even faster boats became available many of the ST 200s were converted into [[fireboat]]s. [[File:HSL 102 at Gosport.jpg|thumb|HSL 102 at Gosport]] The work of the BPBC would lead in the late 1930s to the RAF 100 class High Speed Launch (HSL), based on the elongated hull of a {{Convert|64|ft|m|abbr=on}} [[Motor Torpedo Boat]] the RAF 100 was designed to have a maximum speed of {{Convert|35|kn|mph km/h}}, and achieved over {{Convert|39|kn|mph km/h}} during trials, making it one of the fastest boats of the time.<ref name=RAFASRS1918-1986 /><ref>{{cite web |url=http://www.bmpt.org.uk/other_boats_history/HSL-102/index.htm |title=HSL-102 - 64 ft High Speed Launch |website=British Military Powerboat Trust }}</ref> However, the internal arrangements of the RAF 100 was to prove vulnerable to combat damage, its high deck made the recovery of aircrew in the water difficult, and for wartime use it was underarmed. These shortcomings were rectified in the [[Type Two 63 ft HSL]], nicknamed the "Whaleback" from its deck shape. ===Second World War=== [[File:HSL 164 with RAF Hurricane off Colombo c1943.jpg|thumb|right|[[British Power Boat Company Type Two 63 ft HSL|Whaleback]] high speed air-sea rescue launch ''HSL 164'' off Ceylon in 1943]]As Britain entered the [[Second World War]] the MCS found itself ill-prepared for war. During the [[Battle of Britain]] the MCS could only keep 10 of 13 HSL launches available for [[air-sea rescue]] operations at any one time and the high performance of the craft was brought at the expense of engines which had a service life of only 360 hours. The HSLs were also individually assigned to individual Coastal Command bases, primarily to support the operation of those squadrons based there. Although theoretically available for rescue operations, in general this was done on an uncoordinated ad hoc basis.<ref name=Journal40>{{cite journal |author=Royal Air Force Historical Society|title=Journal 40|journal=Journal|date=2007|issn=1361-4231}}</ref> Even with the help of civilian vessels and the Royal Navy, aircrew who baled out or ditched in the [[North Sea]] and [[English Channel]] had only a 20% chance of being returned to their squadrons.<ref name=RAFASRS1918-1986 /> Between mid July 1940 and October Britain lost 215, hard to replace, pilots and aircrew to the seas.<ref name=RAFASRS1918-1986 /> In light of this, in 1941, an emergency meeting was convened by [[Air Marshal]] [[Sir Arthur Harris, 1st Baronet|Sir Arthur "Bomber" Harris]]. The Royal Navy offered to take over in its entirety the at sea rescue role, the RAF declined and subsequently created the Directorate of Air Sea Rescue on 6 February 1941, which adopted the motto "The sea shall not have them". Operationally it was to become known as Air Sea Rescue Services (ASRS), which later became the [[RAF Search and Rescue Force]].<ref>{{cite news |title=A force for good that's saved 1000s of lives |url=http://www.rafnews.co.uk/readstory.asp?storyID=774&returnto=search.asp&page=4&departmentID=36&categoryID=&search= |newspaper=[[RAF News]] |date=28 January 2011 |access-date=11 March 2011 |archive-url=https://web.archive.org/web/20110218162855/http://www.rafnews.co.uk/readstory.asp?storyID=774 |archive-date=18 February 2011 }}</ref> The headquarters of the ASRS was co-located with that of [[Coastal Command]] with which it was to operate closely. As more High Speed Launches became available these were formed into new dedicated Air Sea Rescue Units (ASRU). Together with the expansion of the ASRS component of the MCS, the ASRS worked to improve the survival of aircrews through the development and issue of better individual survival equipment-including one-man [[Inflatable boat|inflatable dinghies]] for fighter pilots copied from the Germans, the training of aircrew in ditching drills to maximise their chances of surviving to be retrieved, the development and fielding of air droppable survival equipment, and better coordination and collaboration amongst the different services, branches and units in the locating and retrieval of downed airmen. The air-sea rescue squadrons of the ASRS flew a variety of aircraft, usually hand-me-downs rejected or withdrawn from front-line service by the RAF's other branches or, as in the case of the Walrus, begged from the Navy.<ref name=Journal40/> They used [[Supermarine Spitfire]]s and [[Boulton Paul Defiant]]s to patrol for downed aircrew and [[Avro Anson]]s to drop supplies and dinghies. [[Supermarine Walrus]] and [[Supermarine Sea Otter]] amphibious craft were used to pick up aircrew from the water.<ref> {{cite book |title=British Flying Boats |url=https://archive.org/details/britishflyingboa00lond |url-access=limited |last=London |first=Peter |year=2003 |publisher=Sutton Publishers Ltd |isbn=0-7509-2695-3 |page=[https://archive.org/details/britishflyingboa00lond/page/n95 182]}}</ref> Larger aircraft were used to drop [[airborne lifeboat]]s. Although the Walrus and Sea Otters could pick up survivors in calm seas, further out to sea and in rougher waters, it was still not possible for aircraft to routinely pick up survivors, the large flying boats that could do so, such as the [[Consolidated PBY Catalina|Catalinas]] and [[Short Sunderland]]s of Coastal Command, had many other jobs to do and were not always available.<ref name=Journal40 /> The role of aircraft in the ASRS therefore, was to locate downed airmen and to keep them alive, by dropping them survival equipment and stores, until an ASRS launch, or one from the Royal Navy's [[Naval Sea Rescue Services]], arrived to pick them up.<ref name=Journal40 /> Generally MCS launches had responsibility for the Channel and North Sea, and Navy ones for the [[Western Approaches]], although a number of MCS launches were based in Northern Ireland.<ref>{{cite web | url=https://www.niwarmemorial.org/collections/blog/royal-air-force-marine-craft | title=Royal Air Force Marine Craft }}</ref> In addition to more and better "whalebacks", the ASRUs would acquire United States built powerboats under [[Lend-Lease]], known as "Miamis" in RAF service, from the name of their builder. These boats were not used in home waters. In addition to High Speed Launches, the MCS would also acquire larger craft, such as the [[Fairmile D]] derived "115 Foot Long Range Rescue Craft" (LRRC), these traded outright top speed for much better seakeeping and range. The MCS craft also became much better armed, sporting multiple machine guns in powered turrets derived from those found in the RAF's multiengined bombers. By convention craft with weapons in front of the deckhouse are not considered rescue craft, and the MCS craft disposed its armament in the amidships, wing, and aft deck positions. This was achieved despite the ship yards and boat builders of Britain coming under the control of the [[British Admiralty|Admiralty]], and which ensured that the needs of the Navy were met first, for example the MCS's LRRCs, only being delivered once the naval need for [[motor torpedo boat]]s was satisfied. By the end of the Second World War, more than 8,000 aircrew and 5,000 civilians had been rescued, and the MCS had some 300 HSLs and over a thousand other vessels,<ref name=RAFASRS1918-1986 /> located not just in the waters around the United Kingdom, but everywhere around the world. The largest fleet of such rescue craft in the world. This fleet and the RAF sailors that crewed it would contract as Britain entered peacetime, however it continued be found everywhere that the RAF flew over water. On 11 December 1947 the MCS was granted full branch status and on 25 June 1948 the largest of its vessels, of {{Convert|68|ft|m}} or more, were granted the [[ship prefix]] His Majesty's Air Force Vessel (HMAFV). ===Postwar and demise=== As the British withdrew from Empire, and aircraft reliability improved, the need for rescue craft to provide cover for the routes that the troop planes and supply transports flew waned, and with the withdrawal from service of flying boats a large part of the Branch's reason to exist disappeared. [[File:RAF Museum, Colindale, London - DSC06008.JPG|thumb|right|Rescue & Target Towing Launch (RTTL) 2757, built in 1957, in the Grounds of the [[Royal Air Force Museum London]], Hendon]] In the early 1950s, helicopters had begun to replace fixed–wing aircraft and supplement the marine craft in the search and rescue role, with the introduction of the [[Westland Wessex]] and later the [[Westland Sea King]], it was now possible to consider the replacement of marine craft in all sea and weather conditions. However, even into the 1970s helicopters had not completely replaced RAF marine craft, even though, by this time, the Marine Branch craft were becoming increasingly elderly and service in the Branch increasingly unattractive. Physically isolated from the majority of RAF bases and personnel, with the withdrawal of the flying boats and the absorption of Coastal Command into [[RAF Strike Command|Strike Command]], the majority of RAF bases were now inland: the Marine Branch becoming largely forgotten and neglected by the rest of the Royal Air Force. The only interaction between the Marine Branch and the rest of the RAF was when the Branch had to draw supplies from another base, or when aircrew arrived at Mount Batten for safety and survival training. Associating the RAF with the conducting of flight operations, other members of the RAF, like the public at large, were often unaware that the RAF had its own marine craft or why they were needed, and when they did become aware of the fact, found it strange and surprising.

[[File:RAF_4003_A.jpg|thumb|right|Rescue & Target Towing Launch Mk.3 4003 - Halifax]] The last roles for the MCS craft were as [[plane guard|guard]] ships and target tugs for the training of the maritime anti-shipping squadrons of the RAF, and its vessels were designated Rescue & Target Towing Launches (RTTL) to reflect this. In 1986, the Marine Branch was disbanded, the last of the RAF's vessels retired and handed over to civilian contractors for the target towing role. In the rescue role, they were replaced either by helicopters, or by the [[RNLI]], where necessary. </textarea><div class="templatesUsed"></div><p id="mw-returnto">Return to <a href="/wiki/Royal_Air_Force_Marine_Branch" title="Royal Air Force Marine Branch">Royal Air Force Marine Branch</a>.</p> <noscript><img src="https://login.wikimedia.org/wiki/Special:CentralAutoLogin/start?useformat=desktop&type=1x1&usesul3=0" alt="" width="1" height="1" style="border: none; position: absolute;"></noscript> <div class="printfooter" data-nosnippet="">Retrieved from "<a dir="ltr" href="https://en.wikipedia.org/wiki/Royal_Air_Force_Marine_Branch">https://en.wikipedia.org/wiki/Royal_Air_Force_Marine_Branch</a>"</div></div> <div id="catlinks" class="catlinks catlinks-allhidden" data-mw="interface"></div> </div> </main> </div> <div class="mw-footer-container"> <footer id="footer" class="mw-footer" > <ul id="footer-info"> </ul> <ul id="footer-places"> <li id="footer-places-privacy"><a href="https://foundation.wikimedia.org/wiki/Special:MyLanguage/Policy:Privacy_policy">Privacy policy</a></li> <li id="footer-places-about"><a href="/wiki/Wikipedia:About">About Wikipedia</a></li> <li id="footer-places-disclaimers"><a href="/wiki/Wikipedia:General_disclaimer">Disclaimers</a></li> <li id="footer-places-contact"><a href="//en.wikipedia.org/wiki/Wikipedia:Contact_us">Contact Wikipedia</a></li> <li id="footer-places-wm-codeofconduct"><a href="https://foundation.wikimedia.org/wiki/Special:MyLanguage/Policy:Universal_Code_of_Conduct">Code of Conduct</a></li> <li id="footer-places-developers"><a href="https://developer.wikimedia.org">Developers</a></li> <li id="footer-places-statslink"><a href="https://stats.wikimedia.org/#/en.wikipedia.org">Statistics</a></li> <li id="footer-places-cookiestatement"><a href="https://foundation.wikimedia.org/wiki/Special:MyLanguage/Policy:Cookie_statement">Cookie statement</a></li> <li id="footer-places-mobileview"><a href="//en.m.wikipedia.org/w/index.php?title=Royal_Air_Force_Marine_Branch&action=edit&section=1&mobileaction=toggle_view_mobile" class="noprint stopMobileRedirectToggle">Mobile view</a></li> </ul> <ul id="footer-icons" class="noprint"> <li id="footer-copyrightico"><a href="https://wikimediafoundation.org/" class="cdx-button cdx-button--fake-button cdx-button--size-large cdx-button--fake-button--enabled"><img src="/static/images/footer/wikimedia-button.svg" width="84" height="29" alt="Wikimedia Foundation" loading="lazy"></a></li> <li id="footer-poweredbyico"><a href="https://www.mediawiki.org/" class="cdx-button cdx-button--fake-button cdx-button--size-large cdx-button--fake-button--enabled"><img src="/w/resources/assets/poweredby_mediawiki.svg" alt="Powered by MediaWiki" width="88" height="31" loading="lazy"></a></li> </ul> </footer> </div> </div> </div> <div class="vector-settings" id="p-dock-bottom"> <ul></ul> </div><script>(RLQ=window.RLQ||[]).push(function(){mw.config.set({"wgHostname":"mw-web.codfw.canary-78ccbdd6f-x7wtv","wgBackendResponseTime":241,"wgPageParseReport":{"limitreport":{"cputime":"0.063","walltime":"0.085","ppvisitednodes":{"value":418,"limit":1000000},"postexpandincludesize":{"value":17740,"limit":2097152},"templateargumentsize":{"value":6556,"limit":2097152},"expansiondepth":{"value":9,"limit":100},"expensivefunctioncount":{"value":0,"limit":500},"unstrip-depth":{"value":0,"limit":20},"unstrip-size":{"value":469,"limit":5000000},"entityaccesscount":{"value":0,"limit":400},"timingprofile":["100.00% 56.462 1 -total"," 99.86% 56.383 2 Template:Blocked_text"," 43.23% 24.407 1 Template:Colocationwebhost"," 38.52% 21.751 2 Template:Replace"," 37.87% 21.384 1 Template:Hidden"," 16.89% 9.536 1 Template:Tlx"," 13.89% 7.845 1 Template:Hidden_begin"," 2.34% 1.324 1 Template:Hidden_end"," 2.24% 1.267 1 MediaWiki:Wikimedia-globalblocking-blockedtext-mistake"," 1.78% 1.005 1 MediaWiki:Wikimedia-globalblocking-blockedtext-mistake-email-steward"]},"scribunto":{"limitreport-timeusage":{"value":"0.011","limit":"10.000"},"limitreport-memusage":{"value":1043356,"limit":52428800}},"cachereport":{"origin":"mw-web.codfw.canary-78ccbdd6f-x7wtv","timestamp":"20241212162342","ttl":2592000,"transientcontent":false}}});});</script> </body> </html>
