Mine Bomber

The Mine Bombardier is a fleet ship, it passively has three mine layers behind it but only uses one, it costs $2500

It seems really bad for the cost, but it has an activated ability~!

Upon pressing Q with a Mine Bombardier fleet ship active, you'll have the power to place a bombing line, the Mine Bombardier will follow that bombing line, firing all three minelayers at an extremely high firerate of one mine every 0.09 seconds, it will also gain a speed boost moving at five times its normal speed; after using a bombing run it requires 120 seconds to recharge.

It has double the health of the man of war and its mines do the damage of a 3 damage mine layer and normal fire rate; upon dying it takes 180 seconds to recharge
