US approval needed, along with OEM support in integration. SOM seems to be the only option considering that any request for sale of AGM-158 JASSM to Pakistan will almost certainly be declined.
Agreed. F-16 role is primarily air defence since PAF doesn't possess/use HARM, Harpoon, air-to-ground cruise missiles and Durandal with them, AFAIK.
Raad (and later Raad-II) were developed as strategic weapons, i.e., primarily meant to carry a nuclear payload. A smaller version, if developed, will likely come in the ~700-800kg weight class with a smaller warhead (~250kg) and a smaller range, potentially compromising the second strike capability in aerial domain.
Now, if this is what is required, why not acquire the CM-802AKG with local assembly/production rights and label it indigenous?
PN has already done it with C-602 (Zarb), that is operated by the NSFC.
