Operation Deer Horn
|May 15, 2019||Fort Grays Island|
|In his first sortie, Trigger, joining Clown in the Osean Mage Squadron, engages a squadron of enemy Erusean bombers threatening the Fort Grays Island base while learning the basics of combat. The Albatross is sunk by the attack, and radio broadcasts are heard, showing Princess Rosa Cossette D'Elise's declaration of war against Osea.|
|02|| Charge the Enemy|
Operation Eastern Wind
|May 17, 2019||Scofields Plateau|
|Golem and Mage Squadrons attack an Erusean forward air base. While attacking the base, one transport aircraft explodes in a flash of harmful blue light. Erusea launches five MQ-99 UAVs to deter the Osean squadrons, but the Oseans shoot them all down.|
|03|| Two-pronged Strategy|
Operation Dual Wielder
|May 30, 2019||Chopinburg|
| As part of a two-pronged retaliatory strike against Erusea, Golem and other Osean squadrons attack Erusean aircraft in the Chopinburg region to secure air superiority in the area while the OFS Kestrel II launches an air assault on the capital region. Clown and Trigger enter the area to provide support to their allies. Erusea deploys one of the Arsenal Birds, the Liberty, and its MQ-101s to counter the Oseans, decimating Skeleton Squadron in the process. The IUN orders the remaining aircraft to retreat.
Brownie, having taken damage, escapes the area with Gargoyle 1 while Mage assists the remaining Golem and Gargoyle pilots being chased by UAVs. An unknown pilot enters the area and shoots down both Gargoyle 1 and Brownie. The Kestrel II is revealed to have been sunk afterwards.
Operation Lighthouse Keeper
|June 6, 2019||Gunther Bay|
| The IUN sends Trigger to infiltrate Erusean anti-air radar around the International Space Elevator and secure a route to help former Osean President Vincent Harling escape. After infiltrating the radar, Trigger destroys the Erusean anti-air defenses around the space elevator. Sea Goblin lands at the space elevator while Clown, Trigger, Golem Squadron, and Gargoyle Squadron engage MQ-99 UAVs launched from Selatapura.
All of Sea Goblin is killed while trying to extract Harling and Colonel Johnson, a military officer accompanying him. Harling and Johnson commandeer a V-22 and take off from the space elevator under the callsign Mother Goose One while Mage, Golem, and Gargoyle defend it from a large formation of MQ-101s launched from an incoming Arsenal Bird (Liberty). Gargoyle, under secret orders from the IUN, fires multiple missiles at the space elevator that destroy many MQ-101s programmed to sacrifice themselves for its protection. One missile breaks through and causes minimal damage to the elevator.
Mother Goose One's cockpit is hit, killing Colonel Johnson. Harling takes the controls and attempts to return to the space elevator. A second missile is fired from an unknown source and strikes the V-22, destroying it and killing Harling. The Liberty enters the airspace afterwards, forcing a retreat. Trigger is blamed for firing the missile and court-martialed.
Operation High Card
|July 1, 2019||Zapland|
|After joining Spare Squadron as a prisoner for his supposed actions, Trigger is sent with the rest of the squadron to deceive incoming Erusean forces into believing the 444th Air Base is a regular Osean air base. Erusean bombers in the formation cause more damage to the base than anticipated; Spare Squadron is ordered to shoot down all incoming bombers. Trigger shoots down most of the bombers, earning praise from his wingmen.|
|06|| Long Day|
Operation One Pair
|July 4, 2019||Roca Roja|
|The 444th Air Base sends Spare Squadron to investigate the anti-aircraft capabilities of an Erusean air base in Roca Roja.

|07|| First Contact|
Operation Two Pairs
|July 12, 2019||Yinshi Valley|
|Spare Squadron is tasked with destroying a number of Erusean radar sites. Partway through the mission, two friendly recon squadrons are attempting to escape a thunderstorm, pursued by UAVs. Spare Squadron is sent to escort them out and shoot down the UAVs. Following their escape, a Su-30SM appears and shoots down Champ after a brief dogfight and proceeds to shoot down Spare 10 and one of the recon planes, prompting Trigger to engage the Su-30, dubbed "Mister X". The Su-30 and both of its escorts eventually retreat due to the weather.|
|08|| Pipeline Destruction|
Operation Three of a Kind
|July 22, 2019||Artiglio Port|
|The 444th Air Base sends Spare Squadron to destroy a large Erusean oil facility before a sandstorm engulfs the area.

|09|| Faceless Soldier|
|July 27, 2019||Waiapolo Mountains|
|Spare Squadron must take down radar sites to slow down the enemy's anti-air capabilities. The squadron gets ambushed by a group of drone F/A-18Fs pretending to be friendly, but AWACS Bandog is able to ID the foes. Full Band gets tagged as an enemy and is shot down by Count.|
|10|| Transfer Orders|
Operation Full House
|August 5, 2019||Borgo dell'Est|
|Trigger and Count must provide escort for 444th Base Commander Col. D. McKinsey, taking down camouflaged SAM sites and enemy fighters.

|August 19, 2019||Hatties Desert|
| The LRSSG, along with several Osean squadrons, must provide time for Major Deanna McOnie and her team to restore the last remaining Stonehenge railgun to bring down one of the Arsenal Birds.
Several Osean craft, including Fencer, get shot down, Skald and Húxiān take damage and are forced to withdraw, and an Erusean agent kills McOnie's survey team, forcing Trigger and Wiseman to disable the arriving Arsenal Bird (Liberty)'s main propellers while the rest fend off the attacking drones. The railgun fires, bifurcating the Liberty and shutting down all of its deployed drones. This victory allows Osean and IUN forces to retake half of the continent.
|13|| Bunker Buster|
Operation Magic Spear
|September 2, 2019||Sierraplata|

Operation Giant's Step
|September 19, 2019||Farbanti|
|The LRSSG launches from Cape Rainy to provide air support for the advancing Osean military in a battle to take Farbanti, the capital city. After most of the defending Erusean forces are routed, Sol Squadron arrives as Mister X sinks two Osean warships and engages the LRSSG in an intense dogfight while Mister X causes chaos below. Fencer and most of Sol are shot down, leaving only Mister X. Wiseman draws his attention and lures him through the Submerged Area against Count's pleas, getting killed in the process. Trigger then takes command of the LRSSG and engages Mister X in a duel, nearly shooting him down before communications and IFF suddenly break down all over the warzone, later revealed to have been caused by satellites all over the world being wiped out by opposing forces. In the chaos, Mister X retreats.|
|16|| Last Hope|
|October 1, 2019||Anchorhead Bay|
| Strider Squadron must provide cover for a defecting Erusean general and his OGDF escort who is trying to broker peace between the warring nations, currently holed up in a war-torn Anchorhead Bay. As IFF is down due to the the global satellite catastrophe, Strider has to manually identify all unknowns on their HUD in order for AWACS Long Caster to identify them. Throughout the escape, the general elaborates on how the Erusean Radical faction conspired using technology borrowed from Belka to start the war, frame Trigger for Harling's assassination, and manipulate most of the government and military, even the princess herself, to further their goals.
After successfully escorting them to an extraction chopper, Long Caster detects [[anEASA liaison plane]] entering the airspace with four escort aircraft. and Strider is ordered to provide support. The transport comes under fire from a squadron of Erusean conservative fighters blaming EASA for perpetuating the conflict. After fending them off, however, the escorts suddenly target Strider and the liaison plane, and an unknown figure on board the plane reveals that the escorts are actually drones that have gained a will of their own after loss of contact with their human controllers following the satellite blackout. Strider shoots down the escorts as well as a group of MQ-99s that, unbeknownst to everyone (including their controllers), have launched on their own.
|October 10, 2019||Tyler Island|
| The LRSSG heads to Tyler Island to check on Osea's progress of recapturing the island, only to find an anarchic three-way brawl between Erusean Radical and Conservative factions with retreating Osean forces cought in the middle. The LRSSG proceeds to cover the allied retreat, at the same time learning of Erusean war crimes committed on the island against Belkan workers and civilians alike.
After clearing out most of the island, the Scrap Queen contacts the LRSSG about a group of refugees and defectors being escorted by 444th Air Base members and surrounded by Erusean forces. Rosa Cossette D'Elise, whose transport was shot down over the island, throws a smoke canister to mark their position, allowing the LRSSG to save them in the nick of time. One of the defectors reveal to AWACS Long Caster about a pair of SSTO supply ships containing Helios weaponry and fuel for the last Arsenal Bird (Justice) about to launch. Despite their incredible speed, the LRSSG successfully intercept them.
|18|| Lost Kingdom|
|October 24, 2019||Shilage Castle|
|Out of options and with their base running out of supplies, Strider Squadron heads to the former Grand Duchy of Shilage to take over their base for precious ammo and fuel. This leads to a dogfight with Sol Squadron where two of them gets shot down, but the fight is interrupted by Mister X entering the airspace with an X-02S Strike Wyvern and ordering the remaining Sols to retreat. Trigger takes him on in a one-on-one dogfight and eventually shoots him down. Before ejecting, however, Mister X reveals to Trigger his regret of unwittingly playing a part in the Erusean Radicals' plans and begs for him to put a stop to their drone production plans, much to his wingmen's puzzlement. Cyclops Squadron arrives afterwards with the cargo transports.|
|October 31, 2019||Gunther|
| With the Erusean Radicals pushed all the way back to Gunther Bay, a coalition of Osean and conservative Eruseans (including Sol Squadron and the LRSSG, who, along with the coalition, received a message from the Scrap Queen) link up in an attempt to retake the International Space Elevator, finish off the Radicals, and take down the Justice, the last Arsenal Bird. When the initial naval-aerial saturation attack fails, the coalition is forced to fight off a massive combined force of drones and Radical remnants alike until Rosa Cossette D'Elise deactivates the Justice's Active Protection System, allowing the coalition to strike the Justice directly.
In their bid to evacuate refugees, the 444th Air Base gets bogged down by falling drones and Tabloid sacrifices himself to save a little girl from being crushed by falling rubble, sharing his fate with some other refugees. Shortly after the Justice's destruction and the space elevator's recapture, Cossette skydives from the space elevator, just as a pair of ADF-11F Raven drones enter the airspace and wipe out most of the coalition forces, damage Count's F-15 with a missile, and nearly kill Cossette in the explosion. The surviving dozen plus coalition forces retreat with the Oseans regrouping at the OFS Admiral Andersen, a grounded Osean carrier.
|20|| Dark Blue|
|November 1, 2019||Gunther|
| It is revealed by the Scrap Queen that the UAVs, codenamed "Hugin" and "Munin", are planning to use the International Space Elevator to transfer Mister X's flight data that EASA uploaded into them to drone factories all across the Usean continent to bolster their numbers, effectively prolonging the war. To prevent this, the coalition remnants launch one final, desperate assault on the UAVs. Several fighters are shot down in the dogfight, but Trigger eventually downs both of the drones. However, the last drone detaches a smaller but dramatically more agile one similar to the one at Bulgurdarest, this time attempting to learn Trigger's flying style, but the drone is also shot down.
Unfortunately, just as victory seems at hand, Rosa Cossette D'Elise warns the coalition forces of a second detached drone. Trigger and Count chase it down through the undersea tunnel that leads to the space elevator's main chamber and destroy it along with the chamber's five data receivers just seconds away from the transfer. Count, whose engines were damaged by the last drone in a tunnel ambush, makes a belly landing at the chamber while Trigger ascends the elevator's windbreak to escape.
