No you may not. It is very hard to force any starship anywhere when its objective is to run away, especially such a nimble and small ship. Not only that, but you're launching from the planet (or possibly the Ha'tak) and it is already further away than your forces.

I am assuming that with Asgard technology, giving the 302's a functional but very limited hyperdrive is possible. Sep is the one that first mentioned this in the IC and so it is up to him to make a final decision on that. for the moment, the F-302's the Langford has launched can easily piggyback in the Langfords own Hyperspace window, and that is what they will do until Sep gives us a decision.
