In the beginning when the Squadron were still K Flight, they flew ten aged Gloster Gladiators and two even older Vickers Valentias.
These aircraft at that point, though greatly received by the people of the Sudan, were outclassed by the machinery that they had to face.   This disadvantage was though greatly reduced through the skill of the pilots who flew them.

Three Gloster Gladiators flying in formation.    (These planes are shown with the wingtips tethered to each other for training purposes.)

The Gladiator was a single seater fighter and had a top speed of 407 km per hour at 4420 m, a climb rate of 9.5 min to 6095 metres and a maximum range of 547 km.  Ceiling of the Gladiator was 10060m.  Armament consited of four 7.7mm Browning machine guns, two on the nose and the others on the wings.  There is 1 airworthy Gladiator left flying today (July 2001).

The Vickers Valentia was a primarily a troop carrying aircraft, although it could double as a bomber..

Top speed was 193km per hour at 1525m, a service ceiling of 4955 m and a range of 1297 km  The Valentia had  no guns, but could carry up to 2200lb of underwing bombs. It had a 2 man crew, and could carry up to 20 passengers.

  The Tomahawk (or Curtiss P-40 Warhawk as it was manufactured as in America) was a robust plane that flew with distinction through 1941 and 42.
Again a single engine fighter with a top speed of 552km per hour  and a service ceiling of around 10000m and a range of 386km.  Armaments consisted of two 12.7mm machine guns mounted in the nose (visible in the picture to the left, though they were usually removed on RAF aircraft) and four 7.62mm wing mounted machine guns.

The Kittyhawk was a later model of the Tomahawk detailed above, and was again a single manned plane, although it was now used also as a fighter bomber.  Top speed was 690km per hour at 3210m.  The rate of climb was 6 min 40sec to 4500m with a service ceiling of 11630m and a range of 386km.  Armaments consisted of six 12.7mm wing mounted machine guns and a hard point for a 227kg bomb or 197litre drop tank under the fuselage.  Several Kittyhawks are still airworthy and flying today, there is a gallery of photos available by clicking here.
