Book excerpt: The Heinkel He 219 Uhu was a night fighter that served with the German Luftwaffe in the later stages of World War II. A relatively sophisticated design, the He 219 possessed a variety of innovations, including an advanced VHF-band intercept radar. It was also the first operational military aircraft in the world to be equipped with ejection seats, and the first operational German World War II-era aircraft with tricycle landing gear. Had the Uhu been available in quantity, it might have had a significant effect upon the strategic night bombing offensive of the Royal Air Force; but only 294 of all models were built by the end of the war and these saw only limited service.
