In Luftwaffe Im Focus, Edition No. 6 from Start-Verlag (
http://www.luftfahrtverlag-start.de/), there is an article on Kg 100 during January 1944.
The article describes the Hs 293 glide bomb as a controlled SC 500 armor-piercing bomb.
On the mission of 22 january 1944, the HMS Spartan was sunk by Hs 293.
I realize this is not exactlyu on point, but it may be of interest.
