Harry Potter, the-boy-who-live which later on became the-boy-who-conquered has had enough of the wizarding world of Britain.
The Idiots can't seem to leave him alone! After the war they readily condemned him of going dark afraid of the powers he hold and then when an upstart dark lord terrorizes them they came running back to him to make him deal with their shite!
A year after being a decorated auror which saw him manning a desk instead of field work, he left and reintegrate himself in the muggle world but not before liquidating all of House Black and Potters vaults along side vaults of fallen death eaters that became his spoils of war into pounds.
The goblins did try to resist the transfer but they have sworn magical contracts that they can't break though that didn't stop the little buggers from slapping the largest tranfer fee possible but it still left him with almost 56 billion pounds.
He joined Hermione in Cambridge (who also got out after her untimely break up with Ron one month after they started dating due to the git cheating) where the two pursued Engineering, Mathematics, Physics, and just about anything that they can grab their hands on, Harry even volunteered to pay for all of Hermione's education.
This made their understanding of magic broadened as they learn how magic work and how it affect things even in the molecular level, this made the two the most powerful witch and wizard in all time even surpassing Merlin and Morgana making them look like amateurs.
The two heavily invested in the mind arts mastering them to near perfection and by representing their mind as a computer instead of a castle or a house this gave them the ability to retain and recall knowledge at will, which greatly boosted their brain to the next level.
The two also took classes on various martial arts offered by the school like judo, jijutsu, boxing, aikido, fencing taekwondo and karate just to keep themselves fit and ready for anything.
6 years pass and the two was hailed prodigies as they have taken all of Cambridge's courses while having remarkable grade in just a short time, this got the two, various offers from large companies in UK, America and a bunch of other countries in Europe, of course they didn't accept them as the two have plans of their own.
The two prodigies have greatly spent time with each other and so it was no brainer that the two would end up dating.
After that the two decided to settle in london but it was a huge mistake as wizards learned of their dwellings forcing them to move as they can't focus on their various experiments due to the constant buggering of the idiots.
So now we found the two teleported (develop by Harry due to his extreme dislike of wizarding travel) in Portsmouth escaping their would be stalkers.
All around the two, various sailor grinned at the young woman as she cursed like a drunk sailor which made Harry snickered.
"Language Hermione" said Harry as she gave her a grin. Hermione responded by playfully slapping the man's arms as she said "Those Idiots just don't get it do they? A bunch of moron who doesn't seem to get a clue that we're done with them"
Harry smiled and kiss the womans forehead, effectively calming said woman before stating "They're all idiots ever since the beginning love"
Hermione for her part relish on the wonderful hug from her partner and said "Yeah, they really are"
She then turn to look at Harry in the eye and ask the important question. "So where should we go?"
Harry thought for a moment before saying "I think we should leave Britain and maybe go the other side of the pond, where the morons can't find us easily."
Hermione furrowed her brows and said "but they will still find us given enough times and we can't run from them forever." She put her hands on her chin and proceeded to think. "Maybe....No, not p-possible? Is Dimensional travel not possible? But the books and tomes of old hinted on it so is it must be possible?" She blabbed.
Harry snickered and said "well, the idiots have been manipulating dimension since the times of old, surely we, the more knowledgeable bunch can make it so we could travel into another?"
"Yes...Yes, I did a rough calculation and it can be achieve but it'll require enough juice to tear open a dimensional rift and mend it after we are through." Said Hermione, who was getting excited at the prospect of going to another dimension. "The only problem, I can see now is the form of transport maybe we should create a spaceship or something? I've always wanted to construct one." She added making Harry smile at her enthusiastic personality.
Harry looked around to let his mind think for the possible transport device to build, when his eyes landed at the docked Aircraft carrier and a ridiculous Idea started forming in his mind, it was so ridiculous that Harry couldn't wipe the shit eating grin on his face.
Hermione saw her man's grin and a shiver ran through her spine as she look at where he was looking.
She saw a decommissioned aircraft carrier and immediately said "No" to her man. Harry grin just got wider before saying "come on mione! It will be great!"
"No! We will not steal one of Her Majesty Ship!" She once again denied the request prompting Harry to kiss the woman before whispering something on her ear that made her blush. "A magical edition of .....K-kama Sutra?" She meekly said.
Harry nodded and grinned while wiggling his eyebrows. Hermione bit her lower lip as she way the pros and con of having the ship but her mind would wonder off to what her man had whispered before so she finally gave in.
"Fine but will make it a spaceship!" she said, which made Harry grinned even more as he replied "That's better!"
So with that, The two became the proud owner of HMS Ark Royal R09 after a deliberate use of a modified fidelius charm and shrinking charm.
1 year pass since then and we found the two in an abandoned shipyard as they were busily adding the final touches on the carrier, that is if you can still call it a carrier.
The two hundred meter long ship was both awe inspiring and ridiculous as it closely resembled Project Insight Helicarrier of the MCU due to the massive gun emplacements on the ship.
The ship was heavily reinforced with charms such Impervious, Unbreakable, Feather weight charm and much more, while they also made a few modifications on the flight decks with only having one runway, while a hood like impervious glass that can be retracted or close over the flight deck.
Now the ships was both durable and nimble as its four propulsion system were large pulsed plama engine that the two developed by utilizing magics ability to defy laws of physics, which can also rotate to provide forward propulsion for the ship.
Its command deck was removed as it was unnecessary and instead use camera to observe in the fortified bunker inside the ship.
The ship was powered with 4 of their very own reactor that process the energy coming off from one dimension (they found during one failed experiment of Dimensional Drive) that was connected to the reactor though it still irritates Hermione since their reactor although very much powerful and efficient, she still wasn't able to use the full potential of the dimensional energy that the dimension holds.
Moving on, the ship is equip with Four large railguns that use a 100 ton tungsten in 6 percent the speed of light through the use of conjuration and feather weight charm (activated only at launch before canceling in flight), on it's side a compliment of point defence modified GAU-Avenger rotary laser is scattered all over the ship's body to protect it from projectiles.
Rotary Plasma are also on the ship for mid-range combat as well as batteries of anti-aircraft missiles(stolen). There were also torpedo port on the ship but was currently empty as the two prodigy argue about the need for putting too much firepower on the ship.
It's most promising aspect is that a runic scheme was tied to the carrier that acts as its stealth system via modified fidelius and repellant charms as well as reflective screens and heat sink just in case the scheme was breach.
The ship is fully capable of Sea, Air and even Space operations as the ship has fully functional life support system in place due to the harsh conditions of space.
The ship is devided into three levels were the bottom was expanded to enable a forest and magical plants to grow.
The ship's first and second has its own cozy living quarters, a library, laboratory, processing area for Asteriod mining, cafeteria, storage and other stuff that take consideration to their lifestyle.
The ships sensors and navigation was replace with their own developed systems as it utilizes and was heavily influenced by the marauder's map, while an AI they had created from modifying Wizarding portrait name Athena (made from mixing the two prodigies brain) control the entirety of the ship including its weapons and targetting systems.
Now it wouldn't be much of an Aircraft carrier without aircraft so the two once again stole almost three dozens of F-15 eagle, a dozen of V-22 Osprey from military graveyard sites in the US and modifying them to be autonomous while the same charms from the ship were added as well as modifying the hell out of them with plasma turrets and PPT engines for better maneuverability and attack.
Harry also took the time to steal tons of military hardware from every other countries (including ICBM's) without telling Hermione.
The creation of the ships wasn't all smooth sailing though as a dozen times they had a wizard or three milling around town trying to figure out their fidelius hideout (They don't know their specific place but they know its in the area), though Tonks, Andromeda, Teddy and Luna apparated one day and arrive at the shipyard with Luna (not being affected by the fidelius) leading them.
Harry and Hermione was at first shock that their improve wards were breach and they were able to learn of their plan but immediately chalk it all up as Luna's own eccentricity and immediately told the three disconcerted people of the shipyard's secret location.
It was later on found that three wanted to join them in their adventure as living in the Wizarding world has become too much of a hassle for Teddy, which the duo immediately accepted them as the two have long since considered the child as their own.
Tonks smiled at her son who was happily hugging his godfather as she wipe a tear on her eyes as she was very thankful for Harry for being the father figure to Teddy that Remus unfortunately couldn't do anymore.
The group then got themselves situated in the ship as it took off from the ship yard flying and started cruising passing the karman line and proceeding into space.
