(Continuation)

With Hornet and the others we could see them fighting against a huge number of production model ships.

Laffey: Javelin on you left!

Laffey warned Javelin who turn around and saw a shell heading towards her as she jumps out of the way.

Javelin: thanks Laffey.

Javelin said as she then fired torpedoes on the Siren as it sinks.

Hornet:Ayanami have you contacted the fleet of our situation?!

Hornet said as she launch some bombers towards a group of Siren ships.

Ayanami: they should be arriving in about a few minutes we just need to hold on until they arrived.

Ayanami said as she slice a Siren plane in half before firing a torpedo on a carrier.

*Boom*

The Torpedo hits the carrier and sinks it to the bottom of the ocean.

Cleveland: hey Hornet!

Cleveland and the others arrived just in time to help them.

Hornet: glad you could make it Cleveland.

Cleveland: yeah we had to clear some Siren ships before we could arrived here.

Cleveland said as she aimed her cannons on a group of high-class Sirens.

Instead of shells coming out blue beams of laser were fired out of Cleveland cannons.

As it hit the high-class Sirens  and not only pierce through them and hitting over 50 production but destroying them also.

Cleveland:I love the new retrofit big brother gave me.

Cleveland said as she fired another round of beams of laser towards a group of carrier.

Hornet:your not the only one with a new retrofit Cleveland.

Hornet said as she launch several Cosmo Lance.

Her planes then fired several missiles towards a group of High-class Sirens.

*Boom*

The missiles hit its target as the high-class Sirens were destroyed easily.

Y/N had retrofited all of them a few months after the defeat of Sakura Empire.

Granting them to be able to fly into space and due to the fact that they have been retrofited with Y/N most advance tech.

Each one of them could fight against a massive Armada of Sirens like the ones they are currently fighting.

Cleveland class instead of a light cruiser she have become a heavy missile Cruiser.

This Cleveland and her sisters new ship appearance is this one:

And she is able to carry over 100 planes to defend herself if ever there are some enemy planes ambush her.

She can also use this planes to Bomb enemy bases and ships if she is assign on a mission alone.

And now back to the battle we could see here launching 10 Cosmo Lancers like Hornet.

As her planes bombed over 200 Siren production model ships.

*Boom*

Cleveland: I like this planes big brother gave me.

Hornet:dang I'm a bit jealous that you are able to fight with not just your cannons but also planes like mine.

Hornet said a bit jealous but resumed launching more planes.

Denver:didn't big brother said you also have cannons.

Hornet:really how do I summon them I kinda forgot?

Columbia:just say Battlecarrier mode activate.

Columbia said as she fired 20 corrosive missiles on a group of high class sirens.

As it hits the Sirens the missiles exploded into a mini blackhole that pulled the Sirens in it.

Before explodding and destroying 900 production model ships near it.

Hornet:ok got it, Battlecarrier mode activate.

Hornet said as her riggings side suddenly opened revealing 2 Mk-13 double barrel Plasma Railgun and 10 of it are floating behind her.

Hornet:cool.

Hornet said in awe but then snapped out of her trance as she aimed her cannons towards 200 high-class Sirens.

Black beams fired out of it and went straight to the High-class Sirens as it vaporized them.

Javelin: that is awesome!

Javelin said while stars are in her eyes before she snap out of her trance.

And fired a blue beam towards a carrier as it Pierce through it but also vaporizing 10 high-class Sirens heads that were behind the carrier.

Montpelier:we got massive incoming bombers heading towards us!

Montpelier said a she pointed up infront of them.

Hornet:everybody open fire.

Hornet said as they fired upon the hoard of planes heading towards them.

Javelin: Laffey behind you!

Laffey: huh?

Laffey turned around and sea a missile heading towards her she has no time to react as the missile hit her.

*Boom*

Everyone: Laffey No!!!

Everyone looked in horror as they went towards Laffey but when the smokes died down it revealed Laffey ok.

Javelin: Laffey you are okay?

Javelin said as she jump to hug Laffey.

Laffey:Javelin wait!

But it was to late as Javelin smack into a blue Forcefield.

Denver: well that's must have hurt.

Denver said as she took Javelin off from the Forcefield.

Cleveland: you alright Javelin?

Cleveland asked while firing missile on an incoming group of enemy Bombers

Javelin:yeah I am fine but what is that blue wall covering Laffey?

Laffey:I heard from Big brother tha this is called a forcefield.

Javelin: what's a forcefield?

Laffey: a field of energy that surround and protect you from attacks.

Hornet:less talking and more fighting first.

Hornet said as he vaporized a group of high-class Sirens.

They mannage to Repel the first wave of attack but then more Sirens appeared and attacked them but luckily there forcefield are protecting them.

Columbia:Hornet there are more coming!

Hornet:everyone launch your Bombers and bombed them to pieces.

Everyone:roger that.

All of them launch there planes and mannage to Bomb the incoming wave of production model ships.

Cleveland: Hornet, there 10,000 high-class heading towards us.

Cleveland said as she vaporized 500 production model ships.

Just then they saw several lights from behind coming towards them.

Laffey:everyone watch out!

All of them duck down as the beams of light pass through them and hitting the 10,000 high-class Sirens.

*Boom*

And destroying them as B-2 past flew hornet and the others.

Cleveland: hey everyone reinforcement are here.

Hornet:thank goodness they have arrived.

Hornet said while sighing in relief that the fleet has arrived to help them as Belfast appeared along with the others.

Belfast: lady Hornet are you all alright?

Hornet:we're all fine glad you all could make it in time.

Belfast: i am glad you are all okay now then let's do some cleaning.

Belfast said as she fired her cannons a red beams of light went straight towards a group of high-class Sirens.

Enterprise then arrive with Yorktown and the fleet could be seen also from afar.

Hornet:sis you both arrive in time were is big brother?

Enterprise:he is with the commander Hornet.

Yorktown:tell us what have you found Hornet?

Hornet:the Sirens fleet is defending something inside there.

Hornet pointed towards the massive group of iceberg and a large entrance could be seen in the middle of it.

Belfast:do you know what it is inside there.

Belfast asked as she fired corrosive torpedoes on 200 high-class Sirens.

As the poor Sirens get sucked into the mini blackhole before it exploded and killing 3000 production model ships.

Hornet:no, unless we can pass through this Sirens we won't be able to know what is inside there.

Hornet said as she pointed towards the massive fleet of Sirens that are infront of them.

Enterprise: will just have to get through them first then.

Enterprise said as she launch several planes from her 4 launching decks.

Enterprise has also retrofited and her ship has over 4 launching decks now giving her more planes to launch.

Appearance:

Enterprise and Yorktown have the same riggings however Hornet ship is different than her sisters.

Enterprise then took out her bow and fired a blue arrow.

The arrow flew at a speed of 1000 mph as it transform into a bomb and went straight towards the Sirens.

*Boom*

It easily killed over 3000 high-class sirens.

With the Royal Navy we could see Hoo and Wasprite firing a volley of black beams towards a group of high-class Sirens.

Queen Elizabeth:this number of sirens in this area is beyond anything we have encountered.

Hood: perhaps they are building something what ever is inside there your Majesty.

Hood said as she fired a barrage of corrive missile on 300 high-class Sirens.

Queen Elizabeth:perhaps but we must hurry and stop whatever the Sirens are planning.

Queen Elizabeth said as she then fired a black beam towards a group of Sirens.

Warspite:your majesty Javelin has something to tell us.

Warspite said as she vaporized a siren head that was about to attack her.

Queen Elizabeth: what is it that she wants to tell us?

Warspite: why don't you ask her then.

Warspite said as Javelin appeared behind her.

Javelin:your Majesty I have some urgent new you need to hear.

Queen Elizabeth: what is Javelin?

Javelin:Lord Y/N needs to talk to you.

Queen Elizabeth immediately fixed herself before looking at Javelin.

Queen Elizabeth:where is Lord Y/N?

Javelin then gave her a small orb as it glowed before a holographic image of Y/N appear.

Y/N:status report Elizabeth?

Queen Elizabeth: my lord we have mannage to destroy 60% of the Sirens fleet.

Warspite: and they are somehow defending something.

Warspite added as Y/N nodded at this before the image of the battlefield appeared infront of them.

Y/N:I have mannage to map the entire area and there is something really big inside here.

Y/N pointed towards the middle of the battlefield.

Hood:what do you want us to do my lord?

Y/N:I am heading there right now the commander said she want me abd the rest of us to enter there and find out whatever's inside there and if possible we destroy it.

Javelin: what are we going to the Lord Y/N?

Y/N: I want you and the rest of the Royal Navy to make an opening for us to pass through those Sirens me and the res of Eagle Union will cover the air support.

Queen Elizabeth:understood my lord.

Y/N:good now get to it we cant want to waste anymore time.

Y/N then disappeared as the orb float back towards Javelin.

Queen Elizabeth: you heard him everyone make a path.

Royal Navy: yes your Majesty.

The Royal Navy then charge up there cannons and prepared to fire on the Sirens fleet that are blocking the way in.

Back with the Eagle Union we could see them destroying thousands of High-class Sirens.

Yorktown: Hornet aim at the iceberg your left!

Yorktown said as she launch several Cosmo Lancers.

Hornet:got it.

Hornet then turned around and aimed her cannons on top of an an Iceberg.

As it she hits her target the huge chunk of ice fell on a group of high-class siren as they were squashed by the huge ice.

Just then a bomber was going to hit Yorktown.

Hornet: sis look out!

Yorktown wasn't able to react as the Bombers drop it's bombs on Yorktown.

Only fit the bomb to be intercepted by a missile.

Y/N:don't put you guard down Yorktown.

Y/N said as he appeared from above as he was using his new riggings.

He has two carrier launching deck on each sides and 6 Mk16 Four barreled turrent floating behind him while holding a sword.

Yorktown: big brother!

Y/N: alright listen up everyone.

Y/N called the attention of all the Eagle Union ships.

Y/N:the commander has detected a massive structure inside there and we need to get inside all of you shall support the Royal Navy who will be making an opening for us understood.

Eagle Union:Hai!

Y/N:good now all of you shot down those planes.

Y/N ordered before he fired his main guns on a group of Fighter planes.

As the Eagle Union launch there planes and shooting down enemy fighters.

Enterprise appeared behind Y/N shooting a siren that was going to shoot Y/N.

Enterprise:big brother you OK?

Y/N:thank you and yeah I am fine Enterprise can you watch my back?

Enterprise: sure just like the battle in Midway.

Y/N:yeah.

Y/N said as both fired on Sirens that were behind them.

Y/N fired on a Siren Carrier while Enterprise fired an arrow on her left killing a group of high-class Siren.

Then 5000 high-class Sirens were heading towards them.

Cleveland: everyone we got company!

Y/N:guess i have to get serious no then Hypersonic.

Immediately everything slow down as Y/N see everyone stops.

Y/N:let's clean up the trash.

Y/N said as a dash towards the high-class Sirens.

With everyone else they saw Y/N disappear.

Cleveland: were did Big Brother go?

She got her answer when Y/N appeared besides Enterprise as they saw him put his sword back into its sheath.

Yorktown: what did you do big brother?

She got her answer when the high-class Sirens fall into pieces.

Everyone: Naniii!
