The unrealized promise of the Bréguet 1120 Sirocco

How good could the Bréguet 1120 Sirocco have been as a naval fighter?

Potentially very good, thanks to its performance, payload, and growth margin, but it was never developed far enough to prove that promise.

The Bréguet 1120 Sirocco's intended performance included supersonic speed, useful altitude, a credible power-to-weight ratio, and room to carry weapons and later upgrades. Its layout also anticipated features associated with later aircraft such as the Tornado and Mirage F1. Those ingredients suggest a potentially good naval fighter. The absence of completed development and service trials leaves the judgment necessarily provisional.
