By 1944, the Luftwaffe's bombing capability had been severely reduced from attrition across multiple fronts,[30] and despite the advance offered by the pending arrival of production Ar 234s, there was a shortage of experienced pilots. The first unit-level type conversion orders were issued to III/KG 76 in May 1944 and personnel had to be pulled from the front lines and brought to central Germany for aircraft and engine familiarisation,[31] which was facilitated with two-seat Messerschmitt Me 262s.[32]
Challenges were encountered getting the Ar 234 operational, including poor quality of worksmanship, and severe shortages of certain resources, such as fuel.[33] The reliability of the Jumo 004 engines would worsen over time, a trend attributed to using ill-suited fuels.[34] The engines suffered from frequent flameouts and had to be overhauled or replaced after roughly ten hours of operation, although as ground crews became more skilled, the time needed to swap engines was reduced.[35] The aircraft's lengthy takeoff runs were responsible for several accidents and attempts at resolution included improvements to pilot training and the use of jettisonable liquid fuel Starthilfe rocket-assisted takeoff units, mounted under each outer wing.[36] Accidents would often be fatal due to the lack of an ejection seat, the pilot instead having to exit via a highly impractical hatch in the floor.[34]
During August 1944, several of Ar 234 prototypes - including six surviving Ar 234A-series prototypes were dispatched on aerial reconnaissance missions. The seventh prototype would perform the first reconnaissance mission over the United Kingdom by a Luftwaffe jet.[37] These reconnaissance flights helped assess the potential for an Allied naval invasion of the Netherlands.[38] Allied piston-engine fighters proved unable to intercept them, being incapable of matching their speed and altitude.[39]
During the autumn of 1944, the first Ar 234Bs began entering service. Early missions included attacks in the Low Countries, at the Antwerp docks and a Brussels railway station.[40] The type was used directly against Allied units during the Battle of the Bulge, and in January 1945, Ar 234s attacked artillery positions to the north of Bastogne.[41][42] One month later, the Allies were able to capture a crashed Ar 234 after it had been forced down by a Republic P-47 Thunderbolt.[24] The type also saw action in Northern Italy.[43]
Perhaps the most notable use of the Ar 234 in the bomber role was the attempt to destroy the Ludendorff Bridge at Remagen.[44] Between 7 March, when it was captured by the Allies, and 17 March, when it finally collapsed, the bridge was continually attacked by III/KG 76 Ar 234s carrying 1,000 kg (2,200 lb) bombs. Most attacks missed the bridge, and heavy losses were experienced from ground-based anti-aircraft guns due to the low altitude these attacks were made from.[45][46]
By 10 April 1945, 38 operational Ar 234s were reportedly on strength, including 24 reconnaissance aircraft, 12 bombers, and two night-fighters.[45] However, most of these sat waiting for fuel and qualified personnel.
The Ar 234 continued to fly combat missions until the surrender of Germany on 8 May 1945.[45] Several were recorded as having been lost, often destroyed by anti-aircraft guns, or "bounced" by Allied fighters either during takeoff or on landing when the jets were flying slow and straight, and were most vulnerable. This technique had already been used against Messerschmitt Me 262 jet. Numerous examples would be captured by the Allies
