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

Spot it by:

Identified by its mid-wing monoplane layout, fixed spatted undercarriage (unusual for a carrier bomber of this era), radial engine with a large cowling, and three-man crew canopy. Distinguishable from the B5N by its non-retractable undercarriage.

History

Developed in competition with the Nakajima B5N, the B5M lost the primary contract but was produced in modest numbers as a backup type. It participated in the attack on Pearl Harbor and early Pacific operations before being replaced by more modern designs. Its fixed undercarriage was unusual for carrier aircraft of the period.

Variants

The B5M1 was the main production version; no significant sub-variants were developed.

Where you'll see it

Operated from Japanese fleet carriers during the early Pacific War (1941–42) before being withdrawn to second-line duties.
