Since triple JumpMaster Torpedo boats seems to be the new black, I thought I would take a look at some options for countering it. It seems to me like Defenders with some of the new tools from the Imperial Veterans box look like a good counter on paper.

With 2 Evade tokens, 3 Agility and Autothrusters, each Defender should be able to absorb a 4-point hit on the crucial first volley without taking damage. Granted a savy opponent will try and concentrate his fire but even so, you will be unlucky to actually lose a ship to the opening salvo.
Once the opening salvo has passed, you have to try and deny him easy targets. Run rings around him with those white K-turns and try to avoid getting 1 ship in a position where it can be torpedoed by more than 1 U-boat in a single round. Use barrel rolls to stay out of arc where possible as avoiding a torpedo shot entirely is probably better than an extra Evade dice.
Once your opponent has run out of torpedos, keep up the good work to stay out of arc and keep chipping away at those Jump Masters. With 3 agility and autothrusters, a 2-dice PWT is going to struggle to make a mark against the Defenders. Be patientand you should nibble away at those big toilet seats much faster than he damages the Defenders.
The cost of the Glaive is still TBC but even if it costs 34 points instead of 33, you can still fit it in. Juke provides your "ace" with an extra offensive edge without compromising your defense and at a PS where you know you will be shooting first.
PS is marginal since both Onyx squadron and Contract Scouts are PS3. You have only 1 point for an initiative bid so you will need to try and judge whether to shoot first or move first.
Alternatively, accept that you will be flying lower PS ships and switch the Onyx squadron pilots for Deltas. That gives you more points to spend on your "ace". You could upgrade the Glaive to Rexlar or or Marek giving you more solid offensive boosts.
