>>6087303For an approximate reference of how big it is compared to the other ships that Newb has visualized.
The M.A.G gun is so massive, that it requires the Frontal coils to have any form of consistent fire. As it is so large the only ships that have larger M.A.G cannons are the Timur, Hammer and aggressor class cruisers & heavy cruisers.
The optimal doctrine for this ship is hit and run. Since the frontal Coils will quickly be depleted with sustained usage. So captains are advised to "mag dump" and then use their thrusters to get out of firing range before the enemy can return fire. This way the Harbinger can recharge its Coils while out of engagement range and come in for another volley.
Sustained engagements without ani missile and anti-fighter screening are advised against heavily. The Harbinger for these reasons is not advised to get into combat with frigates. A Frigate can pose a high threat to a Harbinger if it isn't able to be shot down within the first volley from the Harbinger.
