AIM-109 Medusa
The AIM-109 Medusa was an update of the Great War-era AIM-104. Designed for launch from small mobile platforms such as starfighters, it was most effective against Covenant single ships such as the Seraph-class Starfighter, being capable on most occasions of destroying it with either a direct hit or a close proximity detonation. The Medusa featured several homing systems to prevent it being jammed by enemy countermeasures, and an advanced HEAT tandem warhead with kinetic energy penetrator. This was most effective at destroying targets with a direct hit but could heavily damage them even with a near miss. The AIM-109 featured both contact and proximity detonation systems, meaning it was more likely to damage a target that was taking evasive action.

AGM-148 Scorpion
The AGM-148 Scorpion was an updated iteration of the earlier AGM-141 Scorpion. Operating exclusively as an air-launched ground attack missile, the AGM-148 Scorpion was a hypervelocity contact/proximity detonated missile; although lacking in agility, its speed and high accuracy virtually guaranteed a direct hit against slow and medium moving ground vehicles and stationary structures. Using the same tandem HEAT/kinetic energy penetrator warhead as the AIM-109 Medusa, the missile featured multiple types of both primary and backup target acquisition sensors, enabling it to thwart most active and passive countermeasures.

ASGM-12 Longbow
The ASGM-12 Longbow was a small antiship missile designed for launch from fighter-sized platforms such as the Longsword. The Longbow featured a comparatively small thermonuclear warhead, although it was encased in a lithium triteride shell, which magnified the blast hundreds of times and gave it strength roughly half that of the much larger Shiva-class Nuclear Missile. The advantage of this was allowing the Longsword to carry munitions capable of more than just denting Covenant vessel's shielding and armour. The Longbow featured advanced guidance and logic systems which enabled it to defeat the vast majority of passive and active countermeasures.

Shiva-class Nuclear Missile
The Shiva-class Nuclear Missile was a starship/starfighter-launched missile with a variable yield thermonuclear warhead, designed primarily for antiship purposes. The power of the weapon was such that a direct hit would disable a fully protected CCS-class Battlecruiser's shields and deal moderate damage to its hull. The Shiva was most commonly deployed from UNSC warships though could also be used by single ships such as the F-352B Longsword-class Starfighter and F/A-361 Scythe-class Interceptor.

Zinko-class Nuclear Missile
The Zinko-class Nuclear Missile was a replacement for the ageing Shiva-class, featuring more advanced stealth, targeting and anti-countermeasure design features, allowing it a far greater chance of reaching its target. The Zinko was most often deployed from UNSC warships though could be launched from ground based facilities also, and larger starfighters could carry it into action if necessary.

BLU-80 Bomb
The BLU-80 was a small unguided bomb used for ground attack on light targets such as infantry and vehicles. The bomb was also effective at tactical strikes such as attacks on enemy airfields or supply stations, or carpet bombing of an area. An optional add-on kit was available which equipped the BLU-80 with a seeker head and control fins, which was then designated the GBU-80 Guided Bomb.

BLU-81 Bomb
The BLU-81 Bomb was a mid-sized unguided bomb that was effective against armoured vehicles, buildings and softer targets. The bomb could be upgraded to the GBU-81 Guided Bomb through optional addition of guidance systems and additional control fins.

GBU-54 Guided Flechette
Although not technically a bomb, the GBU-54 Guided Flechette was a guided munition that gained propulsion from gravity, rather than an internal system. GBU-54 Guided Flechettes were large fin-stabilised metal projectiles, featuring guidance systems and a penetrating tip. The Flechette was designed for launch from high altitude aircraft, where it would fall to the ground, guiding itself down onto its target and gaining huge kinetic energy while in freefall. The Flechette was designed against hardened targets such as the heaviest of armoured vehicles and hardened fortifications, and could also be used to great effect against targets of strategic importance. The GBU-54 featured folding wings and fins which saved space when not in use.

MORAY Spatial Mine
MORAY Spatial mines were starfighter-launched high explosive mines with a very high area of effect, intended for use against hostile single ships. The MORAY featured proximity, contact and remote activation systems, and featured a high explosive fragmentation warhead that could destroy a Seraph-class Starfighter at close range or severely cripple it with a glancing hit. The mine also had rudimentary, though efficient, rapid propulsion systems, to allow it to autonomously approach enemy targets (as determined by IFF checks) and magnetic systems which allowed it to adhere to its target, guaranteeing a kill. The MORAY was coated in stealth ablative coating and other advanced metameterials which allowed it to remain undetected even at extreme close range. It had a kill radius of 150m and a damage radius out to 400m. The MORAY was ineffective against Covenant warships. The Longsword could hold up to 36 of these in its ventral ordnance bay.
