The [[Covenant]] races, meanwhile, have been spacefaring for significantly longer than humanity. The [[Sangheili]] had been a spacefaring civilization for some time by [[938 BCE]], when they encountered the [[San'Shyuum]]. The [[San'Shyuum-Sangheili War|resulting conflict]] was fought on both planetary surfaces and in space engagements, where the San'Shyuum held the distinct advantage due to their use of the [[Forerunner Dreadnought]], a [[Forerunner]] [[keyship]] fitted by the San'Shyuum with offensive armament. In [[1342]], the Covenant fought the many [[Kig-Yar]] pirate and militia groups around [[Eayn]], including naval engagements against space-based raiders in their homeworld's asteroid belt, where their smaller ships and intimate knowledge of their environment benefited the Kig-Yar until they agreed to be employed by the Covenant. Covenant warships also took part in the glassing of [[Balaho]] during the [[Unggoy Rebellion]], though likely faced little serious naval opposition. The [[Jiralhanae]] were a spacefaring species, before they were reduced by their [[First Immolation]] to a pre-atomic stage, and it is likely that this war included space combat.<ref>'''[[Halo 3]]''': ''[[Bestiarum]]''</ref>

The Covenant, on the other hand, employ more arcane weaponry derived from even more advanced [[Forerunner]] technology. The typical offensive armament for a Covenant warship consists of [[plasma torpedo]] turrets and [[energy projector]]s to engage enemy combatants.

The [[Didact]] devised a well-known strategic doctrine known as "[[star-hopping]]" which involved the selective targeting of strategically significant worlds while ignoring less important targets. This strategy allowed the Forerunners to gradually dismantle the prehistoric human empire piecemeal during the [[human-Forerunner wars]], eventually leaving only their capital [[Charum Hakkor]] as a significant military bastion.<ref>'''Halo: Primordium''', ''pages 187-188''</ref> During fleet engagements, the Didact favored the [[fleet spiral]] formation which enabled a fleet to respond to threats from any direction.<ref>'''Halo: Silentium''', ''page 267''</ref> Late into their war with ancient humanity, the Forerunners took advantage of their superior understanding of [[slipstream space]] to catastrophically increase their human opponents' [[Reconciliation|space-time debt]], effectively cutting the [[Charum Hakkor system]] off from the rest of the ancient human empire. Over three years, the Didact fought the [[Forthencho|Lord of Admirals]]' forces across the Charum Hakkor system in a constant battle of attrition for superior orbital paths and optimal slipspace pathways.<ref>'''Halo: Primordium''', ''pages 239-240''</ref>
