Just started flying the dreaded Spitfire in BOE
& am confused by their gun setup.

I think the IXC 1943 was armed with 2 20mm cannon & 4 303 machine gun. What is the IXE armed with & what does LF/HF stand for please?

Have not checked my sources but I think the Mk IX E
was the version armed with two 20mm cannon and two .50 caliber machine guns.

The 'e' winged Spitfires (Mks VIII, IX, and XIV all had some production runs with the 'e' wing) were armed with one .50 cal M2 mounted inboard of the 20mm cannon in each wing (no .303s). I believe that there was also a provision for a hardpoint in each wing for bombs, rockets or possibly, drop tanks.

HF and LF referred to High (altitude) Fighter & Low (altitude) Fighter versions. This was due to differences in how the superchargers were geared, mainly determining at which point the 'high' blower kicked in.

Spitfires designations can be quite confusing sometimes.

Letters C and E are reffering only to armament. C armament is composed of 2 x 20mm Hispano (120rpg) + 4 x .303 Browinig (350 rpg)

E armament: 2 x 20mm Hispano (140rpg) + 2 x .50 Browning (250 rpg)

Letters F, LF, HF etc. are reffering to engine, LF being optimised for low and HF for high level performance. But I don't find difference in performance that big.

At the clipped wing versions there is CW added to designations.

It was the wing not the arment, both wings were capable of multiple arments eg 4 20mm cannon configuration.

As Hell Toupee said - it refers to wings, not armament.

From memory:

A wing - 4 .303s
B wing - 1 20mm, 2 .303s
C wing - 2 20mm OR 1 20mm and 2 .303s
E wing - 2 20mm or 1 20mm and 2 .50s

Since armament has been done I'll report a bit more on the F, LF, HF designations. These are official RAF designations for the different engine types that the Spitfire IX used in operation.

F refers to the early Spitfire IX model with a Merlin 61 engine in it

LF refers to the slightly later Spitfire IX model with a Merlin 66 engine that was tuned to switch to the second supercharger stage (the Merlin 60 series introduced a two stage supercharger) at higher altitudes. In the cockpit on the lower right side of the main panel there is a switch and a light that indicate which stage the supercharger is at (its automatically engaging). The red light will appear above 5000m or so. The reason for the LF modification was to match the Spitfire IX's top speed to be better than the captured FW190A at all altitudes.

HFRefers to a very rare Spitfire IX model using a Merlin 70 engine. It is the exact opposite of the Merlin 66 in that its supercharger stage kicks in at a much higher altitude. The HF is slower than the LF model until about 7500m where it outperforms it significantly. Most Spitfires employed in high altitude operations were used against high flying German reconnaisance aircraft and thus were not really meant for fighter combat but instead for interceptor operations at higher altitudes.

FYI: All Spitfire IX models ingame represent Spitfire LF.IX (Merlin 66) models except for the HF.IXe. Only the clipped wing variants indicate that they are LF.IX but this is wrong. There are no F.IX (Merlin 61) models represented in the game. Also to note, the Spitfire Vb has much the same...a LF and F variant except that the Spitfire Vb's Merlin 45 and 55 engines have a single stage so the engines were tuned for either higher altitude or lower altitude advantage and were not as flexible as the LF.IX.

Think of it like this (in the game. There were F model Spitfires but there are non in the game)

In game Spitfire's :-

LF = Low Flyer
HF = High Flyer

In game Seafire's :-

L = Low FLyer
F= High Flyer

You need to be over 4000m most of the time to have the HF make any sense at all. (not often in the online game as its all about ground targets)


Also I think the missing 'D' wing is the Hurricane IID's 2x40mm cannon. If someone could correct me then please do, I have never found any other possible explanation for the jump from 'C' wing to 'E' wing.

Icefire I can't find anything in the game or readme's to indicate what engines are modelled in the game for the MkIX's. Can you tell me where you got your information from please.

it was talekd and testet in the community since the Spitfries are available in this game.

the documantation of this game is sometimes, well, incomplete ( http://forums.ubi.com/groupee_common/emoticons/icon_biggrin.gif ).
but trust IceFire, he said it like it is in the game.
all Spitfire IX and VIII , except the HF.Mk.IX, are LF variants with Merlin 66............ if they are named so or not

Ok, I posted this in another thread recently, but I guess most of it is relevant here:

There were 4 basic engine types fitted to the Spitfire IX, the Merlin 61, Merlin 63/63a, Merlin 66 and Merlin 70. Each engine bestowed different performance to each sub-type, based on different engine power and full power heights.

F. Mk IXc

Merlin 61 engine, 1,535 hp, +15 lbs/sq.in boost

320 mph at 0 feet
380 mph at 15,000 feet
405 mph at 27,000 feet

Peak RoC: 3,800 feet/minute

Introduced July, 1942

The basic Mk IX that took the fight back to the FW-190 and the allowed Spitfire to roughly regain equality against the newer LuftWaffe machines. Faster and better climbing at all altitudes than the Spitfire V, with very similar turn performance. All flew with the 'C' type wing.



F. Mk IXc

Merlin 63/63a engine, 1,710 hp, +18lbs/sq.in.

325 mph at sea-level
385 mph at 16,000 feet
410 mph at 27,000 feet.

Peak RoC 4,100 feet/minute

Introduced to service in late 1942/early 1943

An improved F. Mk. IX with an uprated Merlin 63/63a engine, allowing higher sustained boost pressure of +18lbs/sq.in. It was around 5 mph faster than the F. IX with the Merlin 61 at all altitudes, and about 200-300 feet/ minute better in the climb.

The Merlin 63 engined variant was the most common type of F. Mk IX, with around 700 of 1,250 F. Mk IXs recieving the Merlin 63 engine. Like the previous Merlin 61 powered variant, it was designed for best performance at 25-30,000 feet.


L.F. Mk IXc/e

Merlin 66 engine, 1,720 hp, +18lbs/sq.in.

335 mph at 0 feet
385 mph at 10,000 feet
410 mph at 22,000 feet.

Peak RoC 4,700 feet/minute

The L.F. Mk IX was a standard Mk IX airframe with a strengthened Merlin 66 and dropped supercharger heights. Designed to perform best at medium altitudes up to 25,000 feet, after the airwar in Europe began to drop away from 30,000 foot engagements around early 1943. Called the Mk IX-B early on by pilots and the RAF, the designation was changed to L.F. IX in late 1943. The L.F. designation can be though of as 'Low Fighter'

The L.F. IX with the Merlin 66 was the most produced Mk. IX, accounting for about 4,000 production airframes, or about 20% of total Spitfire production. The similar Mk XVI with the Packard Merlin 266 had almost identical performance, but was generally fitted with clipped wing tips, extra rear fuel tanks and the 'E' type wing.

Introduced in to service in March, 1943. The L.F. IX used both the C type wing, and the E type wing (after March, 1944).

This is the fighter that we currently have in IL2. Comparisons should not be made with earlier variants.



H.F. Mk IX

Merlin 70 engine, 1,710 hp, +18lbs/sq.in

330 mph at 0 feet
395 mph at 15,500 feet
415 mph at 27,000 feet

Introduced into service in October, 1943.

A high altitude Spitfire IX with a Merlin 70 with different reduction gear rations and higher supercharger heights. Best performance was in the 15 to 35 thousand foot range. It was the fastest Mk IX varaint, capable of over 400 mph at 30,000 feet and 365 mph at 40,000 feet. Peak rate of climb was around 4,500 feet/ minute.

There were only some 400 Spitfire H.F. IX made and only around 5-6 squadrons flew them operationally. The move towards tactical operations by the RAF, the drop in height of the European airwar, the availability of the pressurised Mk VII and the incoming Mk XIV all limited H.F. IX production and service.
