Vickers 'Vampire'...

[Hauksbee 103]

Also from "Jane's Fighting Aircraft of World War I, at first glance, a fairly wicked looking fighter, mainly for the three machineguns mounted in the nose (this prototype photo has only the two). On closer inspection, it was an anachronism. Originally designed as a bomber-interceptor for Home Defense, and later, hopefully, as a 'trench-strafer', it fizzled and died a quiet death.

Curiously retrogressive in design when built in May 1917, the pusher fighter with boom-carried empennage being decidedly passé at that stage in World War I, the F.B.26 single-seat fighter had its nacelle attached directly to the upper wing. The original concept provided for a single 7.7mm Lewis gun, but an additional Lewis had been introduced by the time that the F.B.26 reached Martlesham Heath for official testing in July 1917. Power was provided by a 200hp Hispano-Suiza engine, but inadequate cooling led to the original single flat radiator being replaced by two separate radiator blocks. On 25 August 1917, the prototype was spun into the ground by Vickers' test pilot Harold Barnwell. Nonetheless, a month later, on 19 September, a contract was placed for six examples of a modified version of the F.B.26. The wing structure was completely revised, radiator blocks were attached to the nacelle sides and a larger vertical tail was introduced. Interest in the F.B.26 centered on its potential as a Home Defense fighter, and it was proposed that armament would consist of two Lewis guns coupled with an Aldis sight and capable of several degrees of elevation and depression. However, in order to obtain greater firepower, the nacelle of the F.B.26 was modified to permit installation of an Eeman three-gun universal mounting. The first two F.B.26s had the trio of Lewis guns fixed to fire horizontally, but it was intended that the next four aircraft would have a modified Eeman mounting capable of 45° of elevation.

The first of the modified F.B.26s was flown in December 1917 with a 200hp Hispano-Suiza engine. After testing at Martlesham Heath, this aircraft was assigned to No 141 Sqn in February 1918 for service evaluation. It was concluded that the F.B.26 was unsuited for Home Defense duties and work on the incomplete machines was halted, although the second and third examples had been completed and flown meanwhile. As the basic design was considered to possess potential in the close air support role, the second of the modified F.B.26s was fitted with a redesigned nacelle incorporating amour protection for the pilot and a 230 hp Bentley B.R.2 nine-cylinder rotary. This armored "trench-strafer" was assigned the designation F.B.26A, and, under the official nomenclature scheme introduced in the spring of 1918, became the Vampire II, the F.B.26 being the Vampire I. In the event, the Vampire II had still to be completed by the end of June 1918, and thus came too late on the wartime scene.

Thanks for the post Hauksbee! Vey interesting little beasty. It's also an interesting notation of armor protection and purpose built for ground support use!

Does anybody know what the Eeman 3-gun universal mounting looked like? I've never heard of it, and a quick web scan has turned up nothing.

Hello,

 

Here you go!

Wow, that looks dangerous! I wouldn't want to get into a burst of that craft in my Albatros!

Looks like an ancestor of the Lockheed "Lightning"!

Curiously retrogressive? Well, I do see how that's meant in context, but look at the De Havilland Vampire: a pusher type, (as all jets are) in the same configuration with twin boom and heavy nose armament. Look at the De Havilland Vampire, and instead of regression, you see the Vickers Vampire was actually way ahead of it's time.

• Hardly enough room on the fuselage for squadron markings!

Nice picture, JFM. I'd found that one (it started the whole search) but it was small, and as you can see, the off-side gun nearly blends into the underside of the top wing. So I passed on it. What had me wondering about the gun mount was that I couldn't see how those MG's could elevate to forty-five degrees. On closer re-reading, I now see that "the next four planes" were to receive a modified Eemon mount...and they never got built.

And the rondel on the side of the fuselage...is the white band on the outside? It looks like white/red/blue. If so, I'll bet some young lieutenant got a scorching over that.
