By late 1915, the B.E.2 was proving inadequate in defending itself against German fighters such as the then-new Fokker "Eindecker", leading to increased losses during the period known as the Fokker Scourge. Although by now obsolete, it had to remain on the front line while suitable replacements were designed, tested and brought into service. Following its belated withdrawal from operations, the type served in various second-line capacities, seeing use as a trainer and communications aircraft, as well as performing anti-submarine coastal patrol duties.
