The moment the strange alien vessel emerged in the skies high above Narita, ParaSOL Command and control, situated deep within a mountain somewhere in the Shogunate got a fix, Wide-Spectrum scanner systems adjusted their fix, and zeroed in on the alien vessel.

Chaos, that would be the word that described the activities within the ParaSOL Command and Control as the alien vessel began it's descent. General Naoto Itoh, commander of the Shogunate's Strategic military command brought his attention to the massive screen splayed out before him. His brows furrowed before he turned.
"Ready Anti-Ship defenses, I want missiles zeroed and locked."
"Alien vessel is falling like a rock, but it's starting to show signs of slowing." One of the Tactical officers reported.

All across Shintenchi, Shōri Type-97 Missiles dot the countryside, these radar guided, hyper-sonic, nuclear armed missiles are designed to shoot down enemy starships from fortified ground positions.
In the mountains surrounding the city of Narita, several Shōri missile batteries swiveled to life, moving to zero in and garner a firing solution on the now slowing craft.
Radar lock by now was achieved, but the strange alien vessel was deploying what appeared to be smaller craft.
As these events played out, General Itoh scowled. "Do we still have telemetry of the alien vessel? Shoot the damn thing down!" He shouted, while his tactical officer protested. "It's too close to the city, by the time our missiles make contact, we could endanger civilian lives."
The General scowled, before he called out. "Scramble all aircraft at Narita Regional Air Command, I want whatever those strike craft shot down!"
With an abrupt nod, the Tactical officer turned, relaying the order.

At Narita Regional Air Command, a wing of
Type 99 Hayabusa, or Cosmo Falcons were being prepped and ready for takeoff, a squadron of planes lined up at the runway, cleared and one by one they began to take off. Each Type 99 Cosmo Falcon was a well rounded fighter plane, capable of trans-atmospheric flight. The falcons were armed with six air to air missiles on triple-racks under each wing, as well as two nuclear-capable anti-ship missiles in the fuselage bays, six 30mm Autocannons in two groups mounted inside the wing fairings, and two 12.7mm Machineguns mounted in the nose.
Engines roared to life, while Type-0 Cosmo Zeroes on patrol diverted to close in on the alien craft. While it was following a single message was broadcast to it, and the Teardrop craft that began to enter Narita's airspace.
"Unidentified Alien Ship you are in a no-fly zone, identify yourselves immediately and divert course or you will be shot down." Two Cosmo-Zeroes began to close in from afar on the Teardrop ships approaching Narita, each fighter craft was armed with four 7.62mm Machineguns, and six anti-air missiles mounted under the wings.
"Coming up from the rear, I've got bandits on my console." A pilot radioed.
As the large alien ship sank into the water, a single Shōri type 97 Anti-Ship missile crested over the Horizon, with radar lock it careened at hypersonic velocities towards the alien ship, aiming to impact it before it disappeared.
