Editing V-1 flying bomb (section)

==Design and development==
In 1935 [[Paul Schmidt (inventor)|Paul Schmidt]] and Professor [[Georg Hans Madelung]] submitted a design to the ''[[Luftwaffe]]'' for a [[flying bomb]]. It was an innovative design that used a [[pulse-jet]] engine, while previous work dating back to 1915 by [[Sperry Gyroscope]] relied on [[propeller]]s. While employed by the {{lang|de|[[Argus Motoren]]}} company, [[Fritz Gosslau]] developed a remote-controlled [[target drone]], the [[Argus As 292|FZG 43]] (''Flakzielgerät-43''). In October 1939 Argus proposed ''Fernfeuer'', a remote-controlled aircraft carrying a payload of one ton, that could return to base after releasing its bomb. Argus worked in co-operation with [[C. Lorenz AG]] and [[Arado Flugzeugwerke]] to develop the project. However, the ''Luftwaffe'' declined to award them a development contract. In 1940, Schmidt and Argus began cooperating, integrating Schmidt's shutter system with Argus' [[Spray (liquid drop)#Fuel sprays|atomized]] [[fuel injection]]. Tests began in January 1941, and the first flight made on 30 April 1941 with a [[Gotha Go 145]]. On 27 February 1942 Gosslau and [[Robert Lusser]] sketched out the design of an aircraft with the pulse-jet above the tail, the basis for the future V-1.{{sfn|Zaloga|2005|pp=3–5}}

Lusser produced a preliminary design in April 1942, P35 Erfurt, which used [[gyroscope]]s. When submitted to the ''Luftwaffe'' on 5 June 1942, the specifications included a range of {{convert|186|mi|abbr=in|order=flip|-1}}, a speed of {{convert|435|mph|abbr=on|order=flip}}, and capable of delivering a {{convert|1/2|LT|kg|sigfig=1|abbr=off|adj=on|order=flip}} [[warhead]]. Project [[Fieseler]] Fi&nbsp;103 was approved on 19 June, and assigned [[code name]] ''Kirschkern'' and [[cover name]] ''Flakzielgerät'' 76 (FZG-76). Flight tests were conducted at the ''Luftwaffe'''s {{lang|de|Erprobungsstelle}} coastal test centre at [[Karlshagen]], [[Peenemünde-West]].{{sfn|Zaloga|2005|pp=5–6}}

[[Erhard Milch]], State Secretary in the Reich Ministry of Aviation and Inspector General of the Air force, awarded Argus the contract for the engine, Fieseler the [[airframe]], and Askania the [[guidance system]]. By 30 August Fieseler had completed the first [[fuselage]], and the first flight of the Fi&nbsp;103 V7 took place on 10 December 1942, when it was airdropped by a [[Fw 200]].{{sfn|Reuter|2000|pp=56–59}} Then on Christmas Eve, the V-1 flew {{convert|1000|yd|m|sigfig=1|abbr=on|order=flip}}, for about a minute, after a ground launch. On 26 May 1943 Germany decided to put both the V-1 and the V-2 into production. In July 1943 the V-1 flew {{convert|245|km|mi}} and impacted within a kilometre (1,100&nbsp;yards) of its target.{{sfn|Werrell|1985|pp=41–62}}{{sfn|Zaloga|2005|p=7}}

The V-1 was named by ''[[Das Reich (newspaper)|Das Reich]]'' journalist Hans Schwarz Van Berkl in June 1944 with Hitler's approval.{{sfn|Evans|2008|p=[https://books.google.com/books?id=0XZHSyTLyIMC&pg=PA660 660]}}
