PX212 and PX214 were only partially naval, being outfitted with arrestor hooks but lacking the wing-folding mechanisms of subsequent production aircraft; PX219 was the full naval version and later conducted carrier deck trials on board the aircraft carrier HMS Ocean.
O PX212 e o PX214 só foron parcialmente navalizados, sendo equipados con ganchos de detención pero sen os mecanismos para dobrar as ás dos seguintes avións de produción, pero o PX219 foi totalmente navalizado e despois realizou probas a bordo do portaavións HMS Ocean.
