Messerschmitt Bf 109 Bf 109 G-14

The Bf 109 G-14, which reached the invasion front in France in July 1944, was an attempt to standardize production of the Gustav series after the proliferation of field variants that had sprung from the G-6. It incorporated MW 50 methanol-water injection as standard, raising the output of the Daimler-Benz DB 605AM engine to 1,800 hp (1,324 kW), and the three-panel Erla Haube canopy. It reached 665 km/h at 5,000 m; the high-altitude G-14/AS variant, with the DB 605ASM engine, reached 680 km/h at 7,500 m. It is estimated — with reservations, given the fragility of factory records from the last year of the war — that around 5,500 units were built between the G-14 and G-14/AS, the second most numerous sub-variant of the family after the G-6.
