1941 Lavochkin, LaGG-3 (aka Lavochkin-Gorbunov-Gudkov LaGG-3)
The airframe was partially made of "delta wood": a material composed of very thin layers of birch or pine wood veneer, and a phenol-formaldehyde resin, which together were baked at high temperatures and pressures.
In combat, the main advantage of the LaGG-3 was the strength of its airframe and the fact that it did not easily catch fire, despite the extensive use of wood. However, the laminated wooden panels did tend to shatter when hit by high explosive rounds and Soviet pilots nicknamed the plane Lakirovanny Garantirovanny Grob, or "guaranteed varnished coffin".
Various versions of the V-12 Klimov M-105 engine were used.
