Breguet U2

The Breguet U2 was a pre-war biplane with thin, circular cross-section and a cruciform tail. One escadrille used them from August 1914 through November 1914, when they were replaced with Voisin 3s. They were flown only with "great apprehension".

They served with No.2 and 4 Squadrons RFC (before going to France), where they were nicknamed the "Tin Whistle".
