     "That air combat highlighted the advantages of the Gladiator over the C.R.42, especially radio equipment

that could permit coordinated attacks, and the Gladiator's superior low altitude overall performance, with

markedly superior horizontal maneuverability over the Falshi. The Gladiator was superior to the Fiat regarding

combat equipment also." From: "Gladiator Vs. Falco 1940-41" by Hakan Gustavsson & Ludovico Slongo.

 

     "The Real problem with the Gladiator (WW2) was that its insufficient medium altitude speed rendered almost

impossible the interception of the faster S.M.79s, and in fact during the campaign Gladiators (which lost at

least two of their numbers in the process) only shot three of these machines down." "...against the Glosters

the Italian bombers were able to operate without escort and almost with impunity. On the other hand, the

Fiat fighters and the Falco in particular were much more effective against British bombers, with around

30 Blenheims shot down or obliged to force land or crash land, notwithstanding the highly ineffective

warning network." From: " Desert Prelude Vol.2 " Operation Compass" by Slongo & Gustavsson.

 

And of course all this information was brought to my attention by my good friend Michele M. Gaetani.

The Gloster Gladiator drive train

 

     Information supplied by my good friend Michele M. Gaetani.

 

     " The Gladiator was powered by a 1,520 cu. in. Bristol Mercury VIIIA or IX engine, a shorter stroke

1935 evolution of the renowned Jupiter. A very squeezed-out single row 9-cylinder engine, it gave 840

HP for take-off from sea level up to 1,000 ft. (+5 psi and 2,750 rpm.), maximum continuous climbing rate

was 700-730 HP at S.L. and 795-825 HP at 13,000 ft.(+5 psi and 2,650 rpm.), continuous cruising power was 685 HP at 13,000 ft. (+3.17 psi and 2,400 rpm.), maximum power for five minutes was 840 HP at 14,000 ft.

(+5 and 2,750 rpm.).The Mercury was fairly light (1,065 lbs.) but rather cumbersome (frontal area 14.7 sq. ft.).

Its major weakness was the use of low efficiency fixed-pitch Watts two-blade or Fairey Reed three-blade

propellers.

Gloster Gladiator Timeline

 

March 1934: Gloster begins construction on an aircraft to fit Specification &.7/30.

 

September 1934: 1st flight of prototype S.S.37 piloted by Flt. Lt. P.E.G, Sayer. 

     Engine: Bristol Mercury VIS: 645 hp.

     Armament: 2 x 0.303 Vickers + 2 x 0.303 Drum fed Lewis machine guns.

     Maximum Speed: 242 mph./11,500 ft.

 

3 April 1935: The Air Ministry sponsored extensive trial of prototype S.S.37 now known as K 5200.

 

Late April 1935: Specifications F.14/35 had been drawn up and agreed on. A contract for 23 aircraft

     was awarded to Gloster.

 

1 July 1935: The name Gladiator becomes official.

 

During 1936: The Gladiator entered production at Brockworth.

 

January 1937: The first three production aircraft flew; K6129, K6130 & K6131.

 

16 February 1937: The first batch of Gladiators are delivered to the RAF starting with K6129.

 

22 February 1937: No.72 Sqdn. at Tangmere becomes the 1st to receive five aircraft, Nos.

     K6130-K6134. These were flown to Church Fenton, lead pilot was Flt. Lt. E.M.Donaldson.

     The 1st production batch had the Lewis guns under the lower wings. The Lewis guns were

     seldom used because of service difficulties.

 

2 April 1937: No.3 Sqdn. Stationed at Kenely became the second Gladiator sqdn.

 

27April 1937: No.54 sqdn.stationed at hornchurch is the 1st to receive the Browning-firing

     (4 x 0.303) Gladiators.

 

Note: (A comparison to Bristol Bulldog, Gloster Gauntlet, Hawker Fury and possibly Demon.) 

          Pilots were complimentary of the new fighter, however operational training had a high

     rate of mild accidents. The main flying difficulties were from the increase in wing loading

     and lack of experience in landing with the larger flap area. The Gladiator stalled more

     abruptly, with increased tendency to drop a wing and the relatively easily attained flat spin

     demanded great care for recovery.

 

September 1937: Eight Gladiator squadrons had become Operational: Nos.3, 54, 56, 65, 72,

     73, 80 & 87.

 

Mid 1938: No.80 Squadron operated a detachment of about 3 Gladiators in 'Airpin' operations

     form Ramlech in Palestine against Arab cordon breakers beginning the Gladiator's war in

     the Middle East.

 

October 1939 - May 1940: About 50 Gladiators flew to France to help stop the German invasion.

 

8 April 1940: No.263 Squadron at Filton readied for operations in Finland.

 

The Norwegian Campaign

 

22 April 1940: Eighteen pilots and aircraft headed from Scapa Flow (north of Scotland mainland)

     Norway aboard H.M.S. Glorious. 150 mls. off shore they flew their planes off and landed on

     the frozen Lake Lesjaskog in central Norway.

 

26 April 1940: Last four remaining Gladiators of No.263 Sqdn. flew north to Aandalsnes where

     they were forced to destroy their steeds from lack of fuel that kept them grounded.

 

14 May 1940: No.263 Sqdn. with eighteen replacement Gladiators set sail on H.M.S. Glorious

     for Narvik far to the north.

 

22 May 1940: No.263 Sqdn. arrives at Bardufoss with sixteen Gladiators, two had been lost in

     accidents.

 

7 June 1940: No.263 & 46 (Hurricanes) Sqdns. were evacuated from Narvik landing on H.M.S.

     Glorious.

 

8 June 1940: H.M.S. Glorious was sunk by the Scharnhorst and Gneisenau and almost the

     entire strength of both squadrons was lost. Two pilots of No.46 Sqdn. were rescued.

 

For the Gladiator the war continues:

 

10 June 1940: Italy declares war on France and Great Britain. Gladiators were distributed

     between Malta, Egypt, Palestine, Aden and the Indian Ocean since 1939.

 

1 June 1940: No.94 Sqdn., at Ismailia, handed its Gladiators over to the South African Air Force

     and the Royal Australian Air Force.

 

1944: Numerous meteorological flights in North, East and West Africa, Mosulin Iraq, Gibraltar, 

     Iceland and at hove with the Fleet were still being carried out by Gladiators.
