The plan was to make mini unguided missiles using rocket motor kits like these:

wing mounted launch tubes with guide wire.

Use a spare channel to fire them.

id even designed a simple explosive impact warhead based on a dismantled blankfirer mechanism impact triggered to fire a 9mm blank into a balloon of napalm mix Obviously these days you could use proper explosives
