The, now infamous, C7 Decimator (aided by the D5W Oritos) engaged the dreaded Planet Killer as it closed on the Klingon planet Vorcha. A full spread of drones was launched and the 2 ships in close formation attempted to come around the PK's starboard flank as it appeared to be focused on reaching the planet. At just under overload range, the PK abruptly turned to engage the 2 ships. At that point the C7 captain ordered his ship to turn and engage the PK head on. The D5W followed suit and moved to extreme tight formation (same hex) as ships and PK closed at a combined rate of 6 hex/impulse.
At point blank range (1) both sides unleashed hell. The C7 was the unfortunate recipient of the PK's alpha strike (4xPH4's and 4 PH3's) and was badly damaged (down to 33 power from 55 and massive damage to all hull, aux control, and all other subsystems), with relatively few weapons (1 disruptor and 3 ph) disabled.
The PK did not fair as well as the combined volleys (targeted primarily at the PK's weapons arrays) punched through its shields and armor, taking 75% of the heavy weapons and 100% of point defense ph and 1 of the 4 tractor beams still holding 4 drones at bay, causing still more damage.
With no residual energy available to the PK, the 2 Klingon ships tractored the PK and started pushing it away from the planet Vorcha.
On thrusters alone the C7 managed to put a fresh shield to the PK. Dispite massive internal damage, the PK brought its heavy weapons back up to 50% and fired again at the C7, bringing the fresh shield completely down and scoring minimal internal damage, as the combined remaining weapons of the C7 and still untouched D5W spoke again...silencing the planet killing behemoth forever.
Perhaps 350 pv of ships vs 1 PK is overkill (or in this case 346). 300 would seem to be more of a challenge or even 250. At that level ONE defending ship is GOING to die.
