Sunshark Bomber gets
1. One Markerlight
2. One Missile Pod or you can add a second one.
3. Two MV17 Interceptor Drones each with two ion rifles which gives them four ion rifle shots. Unlike the Razorshark, however, these ion rifles are Rapid Fire 30'', so you can get eight shots out of them, or D3 a piece if you overcharge them.
4. Two Seeker Missiles.
5. Capability of doing bombing runs.
~165 to ~190pts
If you want to bring a flyer, the choice is painfully clear. The Sunshark does everything the Razor shark does, but better.
