It has already been established in Rulesmasters that an energy mine exploding near a stealthy ship will count as an attack for the purpose of reducing stealth; it doesn't matter that the stealthy ship wasn't actually targetted, what matters is that dice were rolled against it.
What about another ship exploding next to the stealthy ship? If a ship has been hit with gratuitous firepower and exploded immediately, and there's a stealthy ship within 4" of it, will that explosion reduce the stealth by 1 as if it had been an energy mine?
