WEFT is AircraftIQ's four-point recognition method — how it works.

Spot it by:

Virtually identical in silhouette to the Me 163 — a short, tailless swept-wing aircraft with a broad fuselage, no conventional tail surfaces, and a distinctive skid undercarriage.

History

Blueprints for the Me 163 were transported by submarine from Germany in 1944, though the submarine carrying the actual aircraft and engines was sunk. Mitsubishi and the Navy reconstructed the design from memory and documents, resulting in the J8M. The prototype's only powered flight in July 1945 ended in a fatal crash, and Japan's surrender came before any more could fly.

Variants

The J8M1 was the Navy version; the Ki-200 was the near-identical Army version. Neither entered production.

Where you'll see it

Never entered operational service; the programme was cancelled following Japan's surrender in August 1945.
