Uhh, ten BFBlues only bring the hull strength down by 5-8%. Death Squad consists of one Tereus, one Phobos, one Argo and one Alcyone. All are using Helios as secondaries; Tereus is using a mix of Blue and Silver beams (this is story related

).
When the Luci first jumped in, the Tereus's front BFSilv got whacked out instantly...

or just failed to fire 'cos the FOV was off. Took me some adjustment to get it to fire...
Point to note, Surkan's Argo is actually pointing in reverse

Front Titan is an anti-fighter grid (AAAf/Hornet/Stinger/Vortex), bottom Titan (which faces backwards when you dock it with the Argo's bottom slot) is an anti-capital grid (BFBlue, Helios).
Sadly I was only successful the first time I loaded the mission (i.e. All Death Squad ships survive and only Lucifer dies)... rest of the times, I had to cheat invul the DS ships, I just couldn't get them to repeat what they did on the first try

Lucifer is one tough mutha...
