Some general information about K4 paint schemes from Wolowski's book "Bf 109 Late versions camouflage & markings". Might be handy for skin makers.

Couple more, this time from JaPo book "Messerschmitt Bf 109K camouflage & marking". Still the best book available about K4 paint schemes IMO.

An account of a combat between a Tempest V of 486(NZ) Sqn and an overall RLM76 K-4 of 13./JG27, 22nd February 1945 ( a little irony in that the Wnr of the K-4 was 331486):

Hello, so bf-109k4 is a late 1944 German aircraft.

 

Main opposition consisting of p-51/47 d American aircraft and Spitfire mk9 and mk14 British aircraft.

 

I read that fuels are limited to B4 for Axis and 100 octane for Allies.

 

So k4 top speed at 1.5-2.25km ranged from 630-640km/h, with a maximum speed of 712km/h at 7.1km Altitude.

 

A safe landing speed of 150km/h thanks to leading edge slats and high chamber wings, combined with an all moving tail plane (flying tail like) controlled by a trim wheel make it an innovative aircraft imo.

 

Just a bit of useless information to spark conversation about the 109 k4 and its competition to come in DCS World.

The 109K-4 had limited ordnance capacity. There were plans for it to carry a 250kg or 500kg bomb, but good luck finding evidence that it ever happened. I also haven't seen 21cm rockets. For obvious reasons the 109K-4 was mostly a dedicated interceptor.

I thought I saw something somewhere for the 21cm, but now maybe it was the G's, Have to look again.. thanks for the info. We definitely need something to intercept....

 

The K-4 cockpit did have the controls for bombs and 21cm rockets as well.

Didn't they have the option for cannon gondolas under the wings for bomber intercept? Granted that isn't explosive ordinance, but just wondering if that was possible to arm on the K4?

If anyone has any good docs on the underwing cannons and wants to share it please do, otherwise I will look around for it. I am positive Yo-Yo already has wind-tunnel data for most external attachements including these...

 

Be interested to see if there was an cockpit mods needed for this.

Does anyone have any good info on ordnance used on the K-4, rockets, bombs etc? I believe the 21 cm rockets were used on it, anything else? Were the R4M ever used on it? What bombs were qualified for it? Anything else?

 

* the ever-present 300 liter droptank of course, feeding into the main tank

 

* 21 cm rockets were installable, as on the G-series. Not sure if that ever happened, given the general lack of use of the rockets by the 109K arrived. The manual says that the option (wiring?) was removed from later production planes, but given that we are getting an early 109K, it seems legit, or at least, fun :)

 

* 2cm Mauser MG 151/20, gondolas guns, 135 rpg, as on 109G (R IV)

 

* bomb sizes up to 500 kg (also 250 kg of course), all sort of types, ranging from the common SC, SD, PC 250 or 500 series. Also by this time the use of the AB series cluster bomb containers was much favored, these were loaded with a large variety of anti personnel i.e. SD 2 "butterfly" boms or anti-tank (hollow charge SD 4 HL) bomblets. Towards the end of the war there was also an increasing use of 109Ks against advancing US Army columns. Cannot recall if the 4x50 kg loadout was still used (given the AB bomb containers being so much more effective).

 

* R4M, no I think, never seen trace of it, perhaps on experimental scale only.

Possible/planned, but rarely used if ever.

 

A few K-4s were delivered with an MG 151/20 in place of the Mk 108, but I'm not asking for that as an option.

They housed one 2cm Mauser MG 151/20 each, percussion firing type, unsynchronized. Tha ammunition is actually stored in the wing in a drum-like ammunition belt container.

.

They had most commonly reported to have 135 round for each gun. Some other sources mention down to 125 and up to 140 rpg.

 

The two guns and their accessorizes weigthed 135 kg, and 215 kg complete with ammunition.

 

The gondolas clean aerdynamic drag was equivalent of +0,0215 sq. meters of Δ[Fcw], or resulted roughly about -8 km/h speed loss at SL. To this needed to be added the increased induced drag resulting from the added weight of 215kg, i.e. roughly equivalent to about - 1,5 km/h at SL and about -6 km/h at rated altitude, as per this January 1944 document:

The harmonization and external ballistics of the similarly armed G-6/U4 m. R VI was as follows:

Bf 109 K-4m W.Nr. 570 xxx "Weisse 6", 9. /JG 4, Germany, Spring 1945, with something under the belly that very much looks like an AB (250?) series bomb container.
