Animation highlighting just one of many revisions to the turbo-pump that occurred at an accelerating rate between August 1943 and late 1944 as the missile moved from development to full production, and finally use in combat. (Digipeer.de images: animation RJD)

Drawing Number: 5741 D3 showing B (fuel) pump centrifugal impeller mpe drawing dated April 1944. mpe original drawing (Digipeer.de image)

Original mpe 1944 drawing number 3207 C of main fuel valave. (mpe = Heimat-Artillerie-Park Karlshagen, Werk Nord Peenemünde).

The injector head section of the 4B 1000kg thrust rocket engine is a precursor to the injector pot or ‘pre-chamber’ design used later for each of the 18-pots of the 25-ton V2 rocket engine. Most of the essential ingredients are shown in this drawing from 1940. Drawing no 1848E Deutsches Museum München online archive ref FA 014/12829

HAP11 drawing of standard 3304D fuel injector screw insert. showing details of primary swirl cavity and orrifice and all additional apertures including the four small cooling pores. HAP11 (Heimat-Artillerie-Park 11, AKA armament code: mpe), drawing number 4554D, Deutsches Museum München

HVP drawing no 1203D showing burner cup ‘diffuser system’ disposition for 19-pot head (at this stage the 25 ton thrust injector head had nineteen so called ‘pre-chambers’ or pots as no central fuel valve was present). HVP drawing dated 1939.

Drawing from the Army Experimental Station Peenemünde dated 1939. The specification describes an insert template that could be used for a range of outlet and inlet orifice sizes. The German text beginning (eingedrehte …) translates as ‘Center-line of screw used for holes to be drilled later’, and the hole dimensions are not specified on this document. HVP drawing number 1113 E, Deutsches Museum München

Sectioned general assembly view of the V2 turbo-pump (TP) dated September 1942. This image has been edited to show TP and document data closer together than the original.

Specification for fuel injector inserts showing orifice size, type, and A to E echelon position. Peenemünde document dated 30th October 1943. Of note on this document is the combination of high and low volume  injector inserts (3304D and 3305D) in the echelon E position of the 12 cups comprising outer ring I. It shows that each cup or pot on this outer ring had 16 inserts at the lowermost position E with 12 of the inserts with three inlet apertures (3305D) and 6 with only two inlet apertures (3304D being lower flow volume) positioned in the segment covering 165 degrees and closest to the outside edge of the head.

Picture shows parts of V2 missile fin structure laying on open ground near area between admin offices and F1 (near Admin. block railway platform, see map).

Picture shows metal debris within the F1 factory boundary walls. The purpose of the part buried liquid storage vessel in the foreground is unknown but it is not a vessel capable of being pressurised. Other assorted metal debris include pipe and cable wall cleats, as well as steel armature rods from reinforced concrete castings (powerful demolition explosions have freed the steel rods from the concrete). These reinforcement rods are a common sight in the environs of Fertigungshalle Eins (F1) and the nearby Repair & Maintenance Hall (R&MH).

This picture shows a small debris field of steel fragments from the V2 missile 130m South-East of F1, and just 20m to the North East of the foundations of a small heat distribution building. Various body and frame parts can be seen and in the middle foreground a 350mm segment of curved missile body ring is visible. These parts have almost certainly been dug up and exposed by the action of metal detectorists. The metal fragments have been abandoned by their finders as they are perceived to have no financial value and hence are not worth removing from the site.

This picture shows a close up detail of parts in a small debris field of steel fragments from the V2 missile 130m South-East of F1, and just 20m to the North East of the foundations of a small heat distribution building. Various body and frame parts can be seen and in the upper left and two segments of curved missile body ring are visible. See previous.

This picture shows the remains of the main South entrance to the Development Works. (also known as Station 7 – Die Hauptwache).

Wooden carboy frame from WW2 (possibly used for transporting small quantities of corrosive and dangerous liquids employed in the V2 steam plant, (such as T-Stoff) laying among trees 190m East of F1 in a location used as an emergency rail freight loading area to F1 due to damage caused by US air raids in August 1944.

This picture shows Robert Dalby collecting GPS data with a mapping camera just North of the East end of the Admin office rail platform (near the ruins of the small admin/F1 heat distribution hub building). In all of our explorations we routinely collect GPS track and data points to be able to accurately locate finds and establish a precise correlation between areas of interest identified on historical reconnaissance photography and the modern ground terrain. In the picture Robert is pointing a Contour video camera at details of the terrain that automatically captures the camera’s GPS location information. This data can then be combined with satellite imagery, via Google maps, and provide a detailed graphic mapping track alongside the video footage.

This picture shows some of the extensive ruins that were once part of the railway shed complex West of the railway lines heading to the Development Works. Screen grab from Karlshagen video.

This video still shows Robert in front of a bomb crater on the West or opposite side of the rail lines and road that pass the Repair & Maintenance Hall (R&MH). The crater like so many others, created in a fraction of a second, in August 1944 during a US air raid, has developed in to a thriving eco-system that now teems with all kinds of life. After the passage of more than 70 years the crater is still deep and well defined. There are hundreds of craters like this in the area.

This video still shows the same bomb crater from a slightly different angle.

After the passage of more than 70 years the crater is still deep and well defined. There are hundreds of craters like this in the area.

This video screen grab shows Robert about to climb the steps up onto the rail and road loading station 9 (also called Die Verladerampen or in English, The loading ramps). This storage and loading facility was never finished during the war and was intended to be a more elaborate with large storage buildings – but the pressure of war and constant use of the area prevented further development. The area is still surprisingly intact today with a strong correspondence between modern ground detail and historical reconnaissance photography.
