Yep, breaching pods "count as if they had the Fighter trait", so they are technically fighters. So not only do they count towards the total for calculating half to begin launched, they can start launched if you like.
For example if you had 12 fighters and 8 breaching pods, total fightes is 20, so you can start with 10 fighters or 5 of each or 2 fighters and 8 pods deployed (or any other combo).
