OK, high drag if you like... But those poor grungy odinance guys on the fields around Port Moresby, (who first started using them) called em parafrags. They were an improv field modification, just like the "gun noses" on the light and medium bombers... They were so effective at destroying Japanese airfields around Buna, Wewak, New Britain, etc, that the factories started building them at home...
Those were the early desperate days of the war.... Our guys in the SoPac were on a shoestring, and had to make do with what they had....
They came up with the most devastating form of attack yet invented....
But High drag works too...
