Ref the JDAMs. Lots of loose talk about converting them to ground-to-ground for UKR rather than air-launched. I confess I have no idea how realistic such talk is.
I believe what you are referring to is Small Diameter Bombs (SDB).
The Ground Launched SDB has already been developed and tested by Boeing and SAAB. However, the GLSDB is a product in search of a customer.
Below is a link to a marketing video by SAAB.
