The V-2 consumed a third of [[Nazi Germany|Germany]]'s fuel alcohol production and major portions of other critical technologies:<ref name=Oberg>{{cite web |last=Oberg |first=Jim |authorlink=James Oberg |coauthors=Sullivan, Dr. Brian R (original draft) |month=March 1999 |title='Space Power Theory |url=http://space.au.af.mil/books/oberg/ |location=[[U.S. Air Force Space Command]] |publisher=Government Printing Office |page=143 |accessdate=2008-11-28 }}</ref> to distil the fuel alcohol for one V-2 launch required 30 tonnes of potatoes at a time when food was becoming scarce.<ref>[http://www.information-britain.co.uk/famdates.php?id=77 First German V2 rocket lands on London]</ref> Due to a lack of explosives, concrete was used and sometimes the warhead contained photographic propaganda of German citizens who had died in Allied bombing.<ref name=
The V-2 lacked a [[proximity fuse]], so it could not be set for [[air burst]]; it buried itself in the target area before or just as the warhead detonated. This reduced its effectiveness. Furthermore, its early guidance systems were too primitive to hit specific targets and its costs were approximately equivalent to four-engined bombers, which were more accurate (though only in a [[Strategic Bombing During World War II#Effectiveness|relative sense]]), had longer ranges, carried many more warheads, and were reusable. Moreover, it diverted resources from other, more effective programs. Nevertheless, it had a considerable psychological effect because, unlike bombing planes or the [[V-1 Flying Bomb]] (which made a characteristic buzzing sound), the V-2 travelled faster than the [[speed of sound]], with no warning before impact, no possibility of defence and there was no risk of attacking pilot and crew casualties.
