The Spitfire's two 20mm cannons were not for antishipping, but for against opposing planes like the Me 109 and Zero (which also had two 20mm cannons each). The Brits found that one 20mm exploding shell could do a lot more damage to a plane than ten rifle calaber .303 MG bullets that they were using, so the Spitfire V and later aircraft had at least two 20mm cannons each. If you look close, you can see where the factory fitted four 20mm cannons plus four .303 MG's per plane. Once in the field though two 20mm cannons were normally removed due to the loss of performance from the extra weight of all four cannons and their ammo (removing two of the 20mm cannons also cut down on the amount of ammo that had to be shipped out to these theators too).

I too really like to Hurricane, but remember, only the early Hurricanes Mk. I's were all fabric (and fixed two prop versus the later adjustable three prop Hurries). The later Mk. I's, Mk. II's and Mk. IV's all had metal wings, but still a fabric fuselage even though the pilot had as much armor around his cockpit as the Spitfire.

This is Milne Bay (Gili Gili) airfield in October 1942. Strangely enough Spitfires never operated out of this airstrip!!

Note also the lack of jungle in the background which probably explains why they were able to do this.




Note the difference between the Spitfire MkVc and the MkVIII in the previous posts. The real difference is the two stage supercharged Merlin engine on the MkVIII as opposed to the single stage supercharged MkV. This can be picked by an extra 8 inches in length (makes the aircraft look a lot sleeker), the four bladed vs three bladed propellor and the six verses three exhaust stubs on each side of the engine. There are also a few visible air frame differences (as Red noted) as the MkVIII had a completely redesigned fuselage.

If you mean Goodenough Island, I'm not sure.

Some pictures in the AWM database show dirt dispersal bays and taxiways but even so there is not much dust even with taxying aircraft. The picture below shows the strip in November 1943 and there is no evidence of any dust. There are other photos of an airfield construction unit (NO. 7 MOBILE WORKS SQUADRON) at work and a gravel quarry so I would say the airfields are well prepared. You will have to look at the photos an decide for youself whether they are sealed or not (unless you can come up with a better reference).
