Generally speaking, javelin torpedoes can be used for level 4 missions, but it requires relatively high torpedo skills because of the use of T2 combat missile launchers.

If cruise is used, although the range is enough, the firepower is seriously insufficient, which affects the efficiency.

Puppet ship plugs are generally large hydraulic cabin thrusters and large rocket fuel isolation buffer devices, plus missile flight speed and missile flight time. This can increase the range of the missile.

Javelin torpedo, the skill is not very bad, generally can hit more than 55KM, enough to meet the needs of level 4 tasks.
