The Stirling had worse altitude performance due to a shortened wing, which was an effect of an air ministry regulation, - i.e. it's original span exceeded the maximum allowable span for aircraft hangars at the time.
Never the less, the first true HEAVY in use. And 60X250 lbs would be quite a thingie.....
A beafighter would also be really nice. A cannon-armed rocked equipped torp carrying plane is one mean piece of muscle we don't have in AH.
