=================================
Pluto
The defenses on Pluto are mobilized as more than 3000 railgun orbital platforms load up a tungsten slug. While on the surface, Everest mass drivers aim up, as they also load up their own tungsten rounds.
Troops on pluto after an extensive exercise under the gravity of pluto go onward to carry supplies in there light weight composite pressurized suits as AMP suits also do the same. With troops in military centrifuge stations train under 2 - 3Gs of gravity.
While this was issued, troops on the surface of Pluto could see a new star in the sky as they knew what was approaching Pluto directly from the direction Neptune was.
First fleet
What was approaching Pluto was the first fleet, made up of 200 Orion class battleships and 299 Enterprise Destroyers. With the remaining being the center of the fleet, the Flagship UNSS-Nimitz. Of the Pershing class super battleship.
The Pershing class was an enlarged version of the Orion class battleship. Measuring at 900 meters in length. And 500 meters in diameter, It carried almost 150 Tyrannosaur Fusion engines and a fully wedged 400 gigawatt Tokamak fusion reactor. It carried almost 2000 Vertical launch systems which were equipped with stacked Inter-Planetary planet busters. And 2 Valkyrie Spacecraft as an evacuation shuttle to ferry its 1200 man crew.
The fleet decelerates its way to Pluto after accelerating for 15 days reaching 1000 kilometers per second before flipping and decelerating. Adding another 30 days to their trip from the Titan colony, spanning 100 thousand people as of now.
The first fleet was also joined with its sister fleet of the same size and composition, the 2nd fleet, from Enceladus colony which housed 8000 people. And the fourth fleet from Callisto, rendezvousing in Saturn's outer orbit.
==================================
Pluto's orbit.
The 1500 ships successfully decelerate into an orbit of Pluto, de-orbiting into the lit up dark side of Pluto as they land on the russian federation sized planet with retractable landing shock absorbers. Into many land based shipyards with tons of trusts everywhere and cranes. And floating worker robots due to the low gravity of Pluto.
Crews of the 3 fleets come out as they swarm the Pluto Defence corp headquarters. With most going to the large underground facilities of Pluto to rest and recuperate from the month long journey.
Admiral Liam Schwartz enters the pentagon of Pluto as he is greeted by General Kanaya.
“General Kanaya, i honor you greeting me once entering the HQ” Liam bows.
“No need for the formalities, come, we are going to my office as I have something urgent to discuss.” Kanaya begins to walk as Liam follows.
Soon they arrive at the quarters of General Kanaya as she sits on her chair and opens a hologram display.
“As you can see Admiral, the tadpoles are nearing the system with a force of almost a million ships. Our oort cloud satellites have detected their movement and are bound to enter the system in 80 hours.” Liam listens as Kanaya moves the display to see the millions of contacts in a very professional formation. Akin to Phalanx formations but in 3 dimensional space.
“I see that general, my British counterpart, Admiral Oliver is gonna confront these beasts with the control of the 5th and 10th fleet as ordered by Fleet admiral Noah.” Liam says as he doesnt get the point of this conversation.
“What I'm saying, Liam, is that you should disobey orders from fleet admiral johnsons orders and assist Oliver. Our yottascale computers assisted with quantum computers predict the battle to be one sided to the tadpoles so i think it's best for you to assist oliver and weaken the tadpoles for pluto to stand with its military force.”
Liam had a confused gazed as he then aggressively said.
“What?! So are you saying you want me to die out ther-”
“Yes! That's exactly what I'm saying! For the hope of humanity even if it will be in vain, but this actually for a secret project NASA is developing.” General kanaya says as she then brought up a holo-ipad and gave it to Liam.
Liam grabbed the Ipad/Tablet in its Remote structure as he pressed a button as multiple lasers simulate a hologram as it showed an encrypted document of the Venture star program.
Liam read through it as he nailed every nook and cranny. Having a very dead inside face as he realized. The US knows we are not gonna survive, and that our militarys only purpose is to slow down the tadpoles.
“As you can see, disobeying Johnson's order is not really disobeying him. As he ordered me secretly to tell you this Liam.” She says as she lifted her legs to the wooden and luxury table to form a cross leg. Where she then took out a vape and inhaled it. Exhaling the aerosal as she closed her eyes.
As for Liam, he already stepped up from his chair across kanayas table and left with the H-pad.
================================================
Earth's L1 lagrange point
Tycho station.
In the largest laser ignition station in the sol system. Its crew was maneuvering everywhere in 0g as they prepared for an external ignition. With a Shepherd class asteroid hauler, hauling a 50 meter long and 9 meters in diameter non thruster active radar guided missile. Hauling it into the correct position as it detached the Missile from its Carbon graphene nanotube cables as the shepherd class retracted it before thrusting away back to Low earth orbit.
The Missile, or nicknamed the mjolnir round retracts from its back side. A 100 diameter sail made of light material.
With protocol starting, the crew is alerted to come to the crew bays as energy from the sun is absorbed and is powering the laser. With metal tubes internally being cooled by cold water while outside, gigantic radiators are radiating heat while the hull integrity of Tycho is filled with radiators.
After 20 minutes, the laser is fired, non visible as it impacted the Solar sail. Accelerating it at an intercept course to the alien fleet.
Unlawfully taken from Royal Road, this story should be reported if seen on Amazon.
Soon accelerating at 15% the speed of light…….. With more rounds being hauled over and accelerated to the same speed.
=======================================
The Alien fleet was decelerating before entering the heliosphere. Thus Fully entering Sol as their magnetic anchors do the rest of the job. Now moving at a constant pace of 500 kilometers per second as they were now heading for Pluto.
But before long, one of the giant flagships of the Tadpoles were suddenly hit and destroyed. With the resulting debri due to the kinetic energy enacted flinging everywhere as it decimates up to 10000 thousand ships. With more and more of these rounds detected on the tadpoles radar.
The tadpoles retract their PDCs as they target all the mjolnir rounds and open fire. With some firing counter-missiles at them.
The 100 Mjonir rounds accelerated, with only 40 remaining as they hit more ships. With the resulting biomechanical debri spreading everywhere as they destroy more than 90 thousand ships. The admiral of the Tadpoles issued an order with its alien tongue and humanoid form as it issued a loose formation making it easier for ships to avoid collateral and friendly fire and harder for these relativistic kill vehicles to target them. And to avoid debri kills.
And in the distance, 3 million kilometers away. The human fleet of the 5th and 10th are accelerating at 1g. Rapidly approaching as Admiral Oliver lays out the plain field within his strategic quarters with other officers. Surrounding an oval table displaying a hologram of the battlefield in a 40 million kilometer diameter 3 dimensional field. All filled with watermelon sized radar and visual detection satellites powered by mini nuclear reactors. All launched and put there before the aliens arrived.
Admiral Oliver stepped forward as he laid out his battle-plan to the 1000 commanders viewing him. Commandeering every ship in the fifth and tenth fleet.
“F10, I want you to flank the enemy from above relative to us. F5 we are going straight forward, F10 shall hold till I say go. As for F5, we will be engaging immediately.”
Oliver maneuvered everything in the holographic display as he positioned F10 to attack the tadpoles or sharks from above. While F5 will be continuing forward, like a bull.
The Vice-Admiral of the tenth fleet salutes as he does what is ordered from the admiral. With the tenth fleet breaking off the loose formation. While F5 is still in its intercept course.
Oliver sends a command through his Pershing class flagship to all ships in the fifth fleet. Which proceeded to every weapons officer in each fleet till more than 5000 Interplanetary missiles launched as their salamander fusion drivers ignite as they accelerate at 20Gs. With RCS thrusters maneuvering these missiles.
The missiles get ever so close to their targets with their active radar guidance system built in. Before being locked and fired upon by hails of bullets as the loose tadpole ships rolled while their hundreds PDC biomechanical Electrothermal 50mm target each Human anti-ship interplanetary missile.
Many of the missiles are destroyed before hitting their targets, with only 600 getting through and managing to hit 550 of the Alien ships and explode its nuclear payload. Creating bright flashes of plasma.
<<550 confirmed hit, 1200 down due to resulting accelerated Debri>>
The assistant officer of Oliver Reports as he continues to survey the battlefield.
All things were going well till the tadpole battleships started to open their Horizontal launch systems as hundreds of alien torpedoes were launched. With these ones using actual thrusters, antimatter engines. With the torpedo covered in a tungsten shell, with the interior showing a biological appearance holding multiple boarding parties of sharks.
These torpedo boarding parties were, of course, detected by the fifth fleet as the 500 ships consisting of Enterprise class destroyers, Orion class battleships, and a single pershing class flagship activated their external PDCs of their own. Aka, the Rheinmetall and general dynamics Napoleon Point defense Cannon.
Every ship was commanded to spin for the better effect of the PDCs as they locked on any Alien torpedo as they fired their 40mm HE Electrothermally.
Dozens of Alien torpedoes were destroyed but 40 went in. With 30 ships breached by these torpedoes, which decelerated for 10 seconds before hitting the composite armor of the Orion classes and Enterprise.

Internal POV
The Torpedo compromised parts of the hull of the Orion class Battleship UNSS-Boris.
Engineers and Armed soldiers supported by robotic drone soldiers come in as they aim at the tip of the torpedo while the engineers carefully approach.
But before long, the tip of the torpedo was ejected through jettison as multiple sharks came out at 8 feet tall. With multiple noticeable cybernetic biomechanical parts as they opened fire by pulling the trigger on there humanoid fingers as the 9mm Automatic rifle surgically ingrained on there arm fired multiple electrothermal propelled rounds.
The sharks came out fast as the engineers died quickly with their EIVA hybrid suit being punctured while the soldiers and drones were not penetrated immediately as they retreated to another hall. Suffering blunt damage from the kinetic force of mach 7 bullets.
As the Sharks cleared the hall, the next set of troopers came, named the “Bugs” standing at 6 feet with 5.56mm Electrothermal assault rifles as they swarmed the hall with the sharks with their hammerhead like receptors where standing while reloading.
As the Sharks and Bugs advance, they are met by hostile forces of humans and robotic soldiers alike as fire fights consume the lower deck of the UNSS-Boris.
“Those sharks and bugs are advancing! Quick! Burst open the cooling pipe!” One of the soldiers orders through their encrypted comms as the drone soldier being controlled remotely proceeds as it makes its way to the hall to be experienced by tons of alien firepower but manages to get a shot before it was destroyed.
The Pipe quickly dissipates very cooled air of liquid nitrogen as it froze and killed many alien sharks and bugs before a Bug sealed it with a sticky attachable polymer.
As the aliens were trying to recuperate after that, the humans went on the offensive as they made themselves visible and burst fires. The Bugs and sharks were caught off guard and were destroyed in this specific hall.
But somewhere else, the aliens dominate as they advance through the ship and bust open the command centrifuge model and blast and kill everyone inside. Including the captain with a thermobaric grenade.

<
Independent capsules on the Boris open as 10 20 meter drones equipped with a single tyrannosaur fusion drive RCS out as they release a magnetic cable and begin to do a burn on a course to pluto. Hauling the UNSS- Boris.
This is experienced with other ships hit as 90% are disabled. With the lucky 10% managing to push back the alien invaders, literally.
The battle continued on as the pershing managed to destroy several of the torpedoes. Like those torpedoes were gonna penetrate its thick armor of multiple composites of chobham, Iridium-titanium, and others like advanced ceramics and Carbon nanotubes, and advanced spider silk carbon fiber kevlar.
With that alien assault out, the tenth fleet was stationed where it was supposed to be as oliver is notified of its arrival to its position.
“Perfect…” he says as he gets into comms with the vice admiral.
“Advance..” That order sent a wave as the tenth fleet launched more than 20000 thousand Ship-to-SHip missiles…….
In the distance, more than 1500 ships entered the bubble of detection into Olivers plainfield as he noticed it to be Liams fleet…..Whats he doing here?
