So something like:

Seeker Missiles / Torpedoes

Cost: 3

Damage: 3

Range: 4+

Attack (Target Lock): Spend your target lock and discard this card to make this attack at Range 4 or beyond (even if the ship is outside your firing arc).

Anything outside of range 3 is simply outside range 3.

A thousand pardons. This should be tidy enough for standard:

Seeker Missiles / Torpedoes

Cost: 3

Damage: 3

Attack (Target Lock): Spend your target lock and discard this card to make this attack at a ship beyond Range 3 (even if the ship is outside your firing arc).
