The vessels are much more even than is being presented, with subcaps lacking the range advantages of capitals (Though http://bg.battletech.com/forums/index.php?topic=53024.msg1386795#msg1386795), and the Merlin having a frightful fore itself.
Not really, here's a breakdown at each range using standard weapons scale (technically the SCL/3s are one hex short of the maximum Extreme range for this scale, but isn't enough to disqualify this as a general example):
(Extreme/Long/Medium/Short)
Lung Wang P2
13
1/16
2/19
3/21
Merlin
00/11/13/18
1: 9 of which is only suffering medium range penalties and can bracket to reduce penalties further
2: 9 of which is only suffering medium range penalties and can bracket to reduce penalties further
3: 9 of which is not suffering any range penalties and can bracket to reduce penalties or gain bonuses.
I'll note that in each case I'm using the nose and one side, it's not until they get to short range that the Merlin's maneuverability will allow it to have any sort of advantage - basically, if it wins initiative when at short range it can avoid most of the Lung Wang's damage, but the same can be said in the reverse. The truth is the Lung Wang P2 has an advantage at all ranges, and significant advantages in the extreme and long range brackets.
Note: Maxxx was correct that both ships are spheroids and thus do not have wings, I had taken that into account when I made my prediction (calculating based off a single side adding to the nose damage), so it doesn't change anything.
