Even if it doesn't mean it, it does a good job at destroying escorts.
In a campaign, a Centauri force of 2 Primus Cruisers and 4 Sulusts, plus a Corvan scout, met a Brakiri force of 10 Ikortas, 6 Brikortas, 2 Aviokis, 2 Brokados and 4 Halik Frigates.
We knew our Centauri ships were probably going to be scrap, but needed to damage to Brakiri enough to force them to halt their invasion (we have our own campaign system, and the Centauri were 8 turns away from starting mass production of the Vorchan after early in the campaign failing to build the appropriate shipyards).
The Sulusts managed to destroy 2 Ikortas, all the Brikortas, a Halik and a Brokados themselves, allowing the Primus's to engage the Avioki's and crush them. In the end, the Centauri were destroyed (except the scout), but only one Avioki, 2 Ikortas and a Halik remained.
The Sulusts were able to use their forward firepower to sweep away any thread to the Primus's while also distracting a large part of the enemy force.
