V-1 (proper name Fi-103)

Payload: 2000 lbs Amatol
Range: 175-200 mi
Propulsion System: Gasoline-fed pulsejet (LOUD)
Launcher: Fixed-site 'ski jump' about 100 yards long
Velocity: < 400 kt (interceptible with Hawker Tempest)
Altitude: usually less than 5000 feet.
Guidance: Simple 2-axis autopilot. Locked elevator in full down
          position when fuel exhausted.
[The first cruise missile]

V-2 (proper name A-4)

Payload: 2000 lbs Amatol
Range: 175-200 mi
Propulsion System: Ethanol (80%) and LOX, pure rocket.
Launcher: Truck-mounted platform.
Velocity: > 2000 kt (detectible on radar but not interceptible)
Altitude: 60 mi at apogee
Guidance: Gyroscopic autopilot with guide vanes in rocket exhaust. 

The V-2 and the SCUD are fairly comparable; the SCUD probably is somewhat
more accurate...I've never seen any CEP estimates for the V-2 but I'd have
to guess it was no better than 2-3 miles, if that good. Because of its
airplane-like altitude and speed, the V-1 was very vulnerable to coastal
antiaircraft fire and fast fighter interception. Some V-1's were downed by
Tempest pilots without a shot--they placed their wing above one wing of the
V-1, breaking its lift and causing it to roll over...the autopilot couldn't
recover from more than about a 15-20 degree roll and the bomb would spin in
to open country (ref: _The Big Show_, by Pierre Clostermann, now Air Minister
of France, then a Free French pilot with the RAF).
