Independently derived from the JN-3, it had a lighter airframe, ailerons on both wings, different shaped wings, stabilizer, elevators and rudder.

Kurt Tank - its designer - had made the aircraft's long range possible by using a light airframe that was two to four tons lighter than its contemporaries.

Because of its smaller, lighter airframe, the Bf 109 was 30 km/h (20 mph) faster than the He 112 in level flight, and superior in climbing and diving.

The Model 147H had the more powerful J69-T-41A engine of the Model 147G, a lighter airframe, and a wing further stretched to 32 feet (9.8 m).

It was based on the early HR100 but had a lighter airframe and new fin and rudder.

The lighter airframe was not enough to overcome the weaker engines, and projected performance suffered compared to La-250.

The JH-7A had a lighter and stronger airframe than the JH-7, allowing the newer aircraft to carry a maximum ordnance load of 9000 kg.

Even with the lighter airframe and supercharged engine, the LaGG-3 was underpowered.

Its lighter airframe gave the new fighter a flexibility that previous models had lacked.

The long, narrow configuration of the V12 contributed to good aerodynamics, while its smoothness allowed its use with relatively light and fragile airframes.
