The 20 mm Hispano cannon were moved outboard and the .50 calibre Browning M2/AN, with 250 rpg were added to the inner gun-bays. The first trial installation (modification 1029) was made in <i>BS118</i> in November 1943; by mid-March 1944 the first service Spitfires to be modified were from 485 (NZ), 222 and 349 Squadrons. Spitfires with this armament were at first referred to as <i>Spifire LF.IX .5</i> and the E suffix was not officially introduced until early 1945.

The longer Merlin 61 meant the nose forward of the engine/fuel tank bulkhead was 7 inches (17.8 cm) longer. An intercooler was mounted behind the engine, on the supercharger casing. A small rectangular air scoop for a "Heywood" air compressor was fitted on the starboard upper engine cowling. </p><p>The carburettor air intake on early to mid-production Spitfire IXs was a different shape from those of single-stage engined aircraft; they were shorter and had a wider air inlet. From 1943, an "Aero-Vee" tropical filter in a long, streamlined fairing was introduced for the carburettor air intake. This was fitted as standard to all Mk VIIs, VIIIs, PR Mk Xs and Mk XVIs, on mid to late production Mk IXs, and to most PR Mk XIs. </p><p>A new 10 ft 9 in (3.27 m) diameter four-bladed <a href="/wiki/Rotol" class="mw-redirect" title="Rotol">Rotol</a> propeller was fitted, housed in a pointed spinner. The exhaust units were changed to six "fishtail" stacks per side. Under the nose, the three piece cowling was changed to a one piece layout. The oil tank was no longer a part of the cowling structure. Early Mk IXs had a teardrop shaped blister (a bulge) for a <a href="/wiki/Coffman_engine_starter" title="Coffman engine starter">Coffman engine starter</a><sup id="cite_ref-12" class="reference"><a href="#cite_note-12"><span class="cite-bracket">[</span>nb 1<span class="cite-bracket">]</span></a></sup>on the lower starboard side cowling, just behind the propeller. This was replaced by an improved electric starter on most two-stage Merlin powered Spitfires and, from late 1942 the blister like bulge was seen on only a few aircraft. </p><p>The <b>Type C</b> wing was fitted as standard. Some mid and most late production Spifire Mk IXs and all Mk XVI were fitted with the <b>Type E</b> wing. While Spitfire IXs converted from Mk Vcs had the large teardrop fairings on the upper surfaces, on the majority of Mk VIIs, VIIIs, IXs and XVIs the teardrop shaped blisters covering the Hispano feed motors were reduced in size and more streamlined than those on the Mk Vc. According to A.P 1565J P & L (Spitfire IX, XI and XVI Pilot's Notes) the red painted undercarriage indicator rods, which projected through the tops of the wings when the undercarriage was down, were used only on early production Mk IXs.

On the wings the ailerons were reduced in span by 8.5 inches (220 mm) outboard of the outer hinges.

In September 1941 the Spitfire Mk III prototype <i>N3297</i> had been converted by <a href="/wiki/Rolls-Royce_Limited" title="Rolls-Royce Limited">Rolls-Royce</a> at their Hucknall plant to take a Merlin 60, which had been specifically designed for use in the <a href="/wiki/Vickers_Wellington" title="Vickers Wellington">Wellington Mk VI</a> high altitude bomber. </p><p> The performance increase was described by <a href="/wiki/Jeffrey_Quill" title="Jeffrey Quill">Jeffrey Quill</a> as a "quantum leap" over that of the Mk Vb and another Spitfire airframe, <i>R6700</i> was modified to take the new engine. Although design work on the Mk VII and VIII series was under way, these would take over a year to get into production and a counter to the Fw 190 was urgently needed. The Air Ministry made the decision that Mk Vc airframes should be converted to take the more powerful engine and, as a result, many of the early Mk IXs were converted Mk Vcs which did not have any of the refinements which later appeared. These could be identified by the Type C wing with the large double blisters over the inner cannon bays and the identification light on the fuselage spine, behind the aerial mast.
