==History== [[File:Formation B-17.jpg|thumb|A B-17E Flying Fortress in use as an assembly ship, wearing a striped pattern paint scheme]] Due to the threat of fighters to US Army Air Force bombers during daylight raids, tight bomber formations began to be employed in order to maximize defensive firepower and to concentrate bombs on the designated target. However, these formations required time to assemble and in 1943 the idea of using older model bombers to guide the others was devised. The USAAF hoped to ideally assemble bomber formations within an hour. However this often required two to three hours as planes from multiple airfields required coordination, all under radio silence so as to not tip off the Germans to the impending raid.

Assembly ships had their armaments removed and carried a skeleton crew of two pilots, navigator, radio operator and one or two flare operators. They were given additional flares, flare ammunition (of a particular color), navigational equipment (including navigational lights)<ref name="MAH"/><ref name="Polka Dot"/> and unique paint schemes. Each paint scheme was unique, and different flare colors were carried by each assembly ship in order to more quickly organize the pilots of a particular bomber formation.<ref name="MAH">{{cite web |title=⚜ {{!}} Why Use Colourful Camouflage in World War 2? - Assembly Ships |url=https://www.youtube.com/watch?v=WYm1QEV69bo |website=Youtube |publisher=Military Aviation History |access-date=2019-02-07 |archive-date=2020-04-09 |archive-url=https://web.archive.org/web/20200409050811/https://www.youtube.com/watch?v=WYm1QEV69bo |url-status=live }}{{Better source needed|date=February 2023}}</ref> Once the bomber formations formed up, the assembly ships would link up with other groups before returning to base.<ref name="Polka Dot"/><ref name="Classic Warbirds">{{cite web |title=The History of Lead Assembly Ships of the Eighth Air Force {{!}} Classic Warbirds |url=https://www.classicwarbirds.co.uk/articles/the-history-of-lead-assembly-ships-of-the-eighth-air-force.php |website=www.classicwarbirds.co.uk |access-date=2019-02-07 |archive-date=2019-02-07 |archive-url=https://web.archive.org/web/20190207205152/https://www.classicwarbirds.co.uk/articles/the-history-of-lead-assembly-ships-of-the-eighth-air-force.php |url-status=live }}</ref> However, there was an instance where a B-24 nicknamed "Spotted Ass Ape" continued with its bomber formation all the way to its target in Germany.<ref name="Polka Dot">{{cite web |title=Polka Dot Warriors > Vintage Wings of Canada |url=https://www.vintagewings.ca/stories/polkadotwarriors |website=www.vintagewings.ca |publisher=Vintage Wings}}</ref> The use of combat boxes and thus assembly ships continued throughout the war even after long-range fighter escorts like the North American P-51 Mustang and Lockheed P-38 Lightning were put into service.<ref name="MAH"/>

==Recall aircraft== A similarly painted aircraft called a '''recall aircraft''' existed at primary training fields in the United States. Due to the fact that PT-17s lacked a radio, an aircraft specially painted with stripes was used to indicate that students should return home if there was bad weather or another emergency.<ref>{{cite book |last1=Mayborn |first1=Mitch |last2=Bowers |first2=Peter M. |title=Stearman Guidebook |date=1973 |publisher=Flying Enterprise Publications |location=Dallas, Texas |isbn=0-912470-01-1 |page=47}}</ref>
