PWS-10 & PWS-15

The PWS-10 was a Polish fighter aircraft.

It was the first Polish designed fighter to enter serial production.

A variant of PWS-10 was a biplane PWS-15, being a PWS-10 with another pair of wings.

A single prototype was made to compare with a monoplane on the factory’s initiative.

It first flew in the spring of 1931.

It offered better manoeuvrability and climb ratio with a slightly lower maximum speed.

PWS-15 was not produced and was soon broken up.
