This page serves as a repository for cutaway diagrams and photos of the V-2/A-4.
This diagram shows a cutaway of the engine compartment. The instrumentation compartment, outlined by the "A-B-C-D" just aft of the warhead, is not cut away in this diagram, but the access panels are open on the V-2 at the Kansas Cosmosphere.

I pointed out how nice the cutaway V-2 diagram above was; the document's authors thought it was so nice that they decided to reuse it, not once, but twice!
Back in the 1940s, the 200-mile range V-2 was considered a "Fernrakete", or "long-range" rocket, while today 200 miles barely qualifies as a "short-range" missile.
Here's a series of drawings which would seem to all be based on the same original, yet are all slightly different.
The first was appeared in a report prepared for the U.S. government shortly after the war by North American Aviation, Inc. During the war NAA made such legendary planes as the P-51 Mustang and the B-25 Mitchell. After the war, they were given V-2 hardware. A division which would go on to become Rocketdyne reverse-engineered the engine, made their own copy, and then went about improving it to create such early engines as the engine for the Navajo cruise missile and the A-7 Redstone. engine.
This diagram has a few callouts:
- 4 Stabilising Fins
- 4 Internal Control Vanes
- 4 External Control Vanes
- Combustion Chamber and Venturi
- Turbine and Pump Assembly
- Liquid Oxygen Tank
- Alcohol Tank
- Control Compartment
In addition to the callouts in the above diagram this one contains many more:
- Chain Drive to External Control Valve
- Electric Motor
- Burner Cups
- Alcohol Supply from Pump
- Air Bottles
- Rear Joint Ring and Strong Point for Transport
- Servo-Operated Alcohol Outlet Valve
- Rocket Shell
- Radio Equipment
- Pipe Leading from Alcohol Tank to Warhead
- Nose Probably Fitted with Nose Switch, or other Device for Operating Warhead Fuze
- Conduit Carrying Wires to Nose or Warhead
- Central Exploder Tube
- Electric Fuze for Warhead
- Plywood Frame
- Nitrogen Bottles
- Front Joint Ring and Strong Point for Transport
- Pitch and Azimuth Gyros
- Alcohol Filling Point
- Double Walled Alcohol Delivery Pipe to Pump
- Oxygen Filling Point
- Concertina Connections
- Hydrogen Peroxide Tank
- Tubular Frame Holding Turbine and Pump Assembly
- Permanganate Tank (Gas Generator Unit Behind this Tank)
- Oxygen Distributor from Pump
- Alcohol Pipes for Subsidiary Cooling
- Alcohol Inlet to Double Wall
- Electro-Hydraulic Servo Motors
- Aerial Leads
I suspect the clerk who typed the captions on this diagram copied them from the diagram below, as there are a few typographical errors and at least one place where a misspelling crept in because of a smudge on the diagram below. The diagram itself also contains the British spelling of "stabilising."
However, this diagram does have an additional detail neither the one above nor below has: This diagram has aerial leads (#30) on the tailing edge of the "stabilising" fins.
The same basic diagram as the U.S. Army diagram above, but a different scan. This diagram is higher resolution and shows things like the Nazi insignia on the German officer's uniform (although I suppose it may have been purposely removed in the U.S. Army diagram above) but oddly shows only a few of the rivets on the fins, which are easily visible above.

- Electro Hydraulic Servo Motors.
Here's another "skin peeled away" type diagram, as opposed to a line drawing. The photo I scanned appeared to have been a photo of a photo, where the original photo or diagram was not flat; close inspection of my scan shows various areas where the focus is soft.
