Possibly, but not exactly. Requirement is for two missile boats in a lance, so two Valks would definitely work. Instead of how a typical Fire Lance works, this formation gets a building to-hit bonus for every unit that scores a hit that round.
First lance member would get no bonus. Provided that lance member hits with a weapon, the next member gets a +1 to hit mod on the same target, and it is cumulative. So if the first three lance mates score some kind of hit, the final lance member would be at +3 to hit mod. Situationally very strong.
