Believed to have been first tried within the first six months of 1916, future German rocketry pioneer Leutnant Rudolf Nebel, then flying as a fighter pilot with Jasta 5, one of the earliest German fighter squadrons within the Luftstreitkräfte, used a Halberstadt D.II aircraft of that unit in the first known German attempt at arming an aircraft with wing-mounted rockets as long range armament.
Leutnant Nebel used a set of four improvised tubular launchers, two mounted per side on the wings, with a signal rocket being fired from each tube for the unofficial trial.
According to Leutnant Nebel's apparently "undated" account, he took off on a defensive mission when 25 Allied aircraft appeared in the air near Jasta 5's base.
He managed to fire his improvised rocket armament at a distance of 100 m (330 ft) from the Allied fighter formation, in a "head-on" attack at it and scared one British pilot into surrendering as the British aircraft landed safely in German territory, with Leutnant Nebel landing no more than 20 m (70 ft) away, to ensure the British pilot's capture.
Just over a week later, Leutnant Nebel used his improvised rocket armament again and blew the propeller off an Allied aircraft, causing it to crash land.

In mid-October 1916, another attempt was made to arm a Halberstadt D.II with rockets, this time for observation balloon attacks with a more formal method, using eight Le Prieur-like rockets mounted on the outer wing struts, the way that the French Nieuport 11 had been armed nearly a year earlier.
Problems with the ignition system on the rockets prevented the system from being experimented with any further.

In late 1916, the Halberstadt D.II was the first known aeroplane for an official trial, with a special unit named the FT-Versuchsabteilung (Radio Telegraphy Experimental Detachment), with the "FT" possibly meaning Funk-Telegraphie, of air communications using radio communications (via Morse Code) in directing fighter aircraft.
IdFlieg sanctioned the test, which resulted in the creation of a radio-telegraphy transceiver for the flight leader's aircraft, weighing 25–30 kg (55–60 lb) along with the battery, aircraft engine-driven generator and aerials.
Receiving gear for the other aircraft in a combat formation was similarly devised, with the radio receiver weighing 12.5–15 kg (27.5–33 lb).
By early 1917, the FT-Versuchsabteilung was making combat trials with the radio gear with Halberstadt D.III and D.V aircraft and by late September 1917 with the famous Jagdgeschwader I unit commanded by Manfred von Richthofen, especially Jasta 4.
Later trials using the more advanced Albatros D.III and Albatros D.Va fighters used the gear for the first attempts at an air-based version of ground-controlled interception of Allied bomber aircraft, using visual ground spotters as the ground component by the home defence Kampfeinsitzerstaffel units.
