A/N So I'm kinda just winging this at the moment, as this is my first story here. Despite that, I aim to succeed, and I'm probably going to be rapid-fire releasing a few RWBY AUs and crossovers (the Division and Bloodborne) within the next few weeks, and try to constantly update them. I had the idea for a Battleship AU a few weeks back, and decided to write something on it. This AU takes place in what would be our 20th century, with technology at about a WWII level, and it will be about 90% on sea, or naval bases. I'm also seeking any suggestions for characters' ships, as I already have all of team RWBY and CRME planned out, along with Pyrrha's and Nora's and Neo's.

Anyway, here goes!

The waves were eerily calm as the moon rose towards the sky, the full, shattered form casting its light over the black waters below it. The waves splashed up and against the steel fortress as it sliced through, eerily silent despite its own weight and power. The Valean Naval Ship (VNS) Crescent Rose was a Beacon-class ship, reserved for the Huntress/Hunter-class squadrons that exist for the sole purpose of seeking out and destroying enemy Admirals and Naval Bases. The Crescent Rose, along with the whole of RWBY Squadron, was unique in the fact that its commander, Commodore Ruby Rose, was the youngest in the world. She had passed her exams with flying colours at a young age, and graduated from the Naval Officer School at the young age of twenty, given her first command (the VNS Crimsonnette) under her mother, who had served on the Hunter Squadron STRQ, and was escorting Ruby to Beacon Naval Base when they were ambushed, three years prior.

Here she was once more, the rest of her Squadron lay at anchor a few hundred metres to the stern of the Crescent Rose as she sailed towards Summer Rose's final resting place, where a buoy had been placed by Ruby the year she was given her battleship. A small launch would depart from the hulking, yet sleek, black mass, the noise of its engine just barely audible over the silence that seemed all consuming. Aboard, only a single figure, clad in a crimson red and midnight black uniform, black hair streaked red and a small ship model in hand, a model of Summer's ship, to be set on the buoy and replace the one left the year prior.

"Here I am, Mom. I made it, just like you said I would. I've got my own ship now, just like you did. Yang's doing well, you should see her now. I'm sure you would be proud. I'm the leader of our squadron, we're a pretty strange bunch." Her hands would fall back to their sides, the small ship set down at the console of the launch, seemingly about to tip over.

"You know that giant Dust corporation, the Schnees? Weiss, the youngest daughter, she's on my team. She fights well, and she may seem icy and mean but she just takes some getting used to. Our resident Faunus, Blake, boy is she an enigma. She's some kind of feline, I think she looks like a panther, which is kind of ironic considering our job. But yeah, I just wanted to stop by, and let you know what's been going on lately. I love you, and I'll always miss you. I'm sorry I couldn't do more to save you." Hands once constantly in motion would fall down to the model ship, picking it up and gently holding it, fingers running along the sleek, metallic form.

She would set the figure down in the water, watching it bob in the waves, resting against the buoy as it was pulled closer by a magnetic device she'd created. She visited this spot yearly, to remind herself of the biggest moment in her life, when she had lost the most important person in her life.

Line Break: A few years prior

"I'm so proud of you, little Rose!" The female figure exclaimed, a wide smile adorning her face. In stark contrast to the shorter figure, her uniform was a bright white, with crimson trim, and her hair was almost the exact same were it not a few tones darker of red. She would reach down and ruffle the shorter figure's hair, eliciting an annoyed groan as her hand was smacked away playfully.

"Mom! Don't embarrass me in front of Uncle Qrow and Dad too!" The shorter figure whined, silver eyes locked onto the older women's in a form of pout before she was lifted of her feet by a tall, larger blonde male. She squealed in surprise, trying to get herself down as she was carried off of the dock and onto the ship that had been put under her command until she could travel with her mother and father to Beacon Naval Base for her assignment.

"We're both excited for you Rubes, but the sooner we get there the sooner you can see Qrow and your sister. Just stay right between your mother and myself while we're out there, understand? It will take a few weeks for us to sail all the way up the coast to Beacon." The male would say, a smile on his face and mirth lighting his azure eyes as his daughter nodded emphatically.

"Sure thing dad! Captain Ruby Rose is ready for action, Taiyang Xiao Long!" She shouted, running to the bridge of her small cruiser, the Crimsonette, in anticipation of their journey. Little did she know just how much excitement she would get.

Line Break: Present Day

"Yang keeps asking me what happened that night. I want to say something to her, really I do. I just… I still can't bring myself to talk about that night without breaking down. I still haven't found anyone to rely on after you met yours, and after dad spiraled like a plane. We have a lead though, one of that cruel witch Salem's associates defected, and right now we're going after Mercury Black. I'll get Salem for you, mom. She won't hurt anyone I care about, not again."

A few tears would be shed by Ruby, her attire becoming wetter as time went on, both of her own volition and as the sea spray collected on her attire. What felt like hours, but was in fact only minutes, after her arrival, she left and returned to her ship. Once on the bridge, she sent out a single message to her friends, her squadron. The message was sent via Morse code, the lanterns aboard her ship making sure the message made it to each of the ships around her.

"Let the hunt begin."

A/N: Let me know what you thought! This is on the shorter side of what I hope these chapters to be, and I promise all regarding the Admirals and squadrons will be explained. The whole tale about how Summer was lost will be explained whence I decide what ship/OT3+ to do this as, or to not do it with any ship (even though it is a seaborne fic ahaha). I'm probably going to post a poll for each of my upcoming stories on shipping decisions, and depending on the top three characters shipped with Ruby I may make it a single ship or multiship, although the polls may be of ship names. I am also currently seeking a beta reader/an editor, so feel free to blame any mistakes in story on me haha. I hope you enjoyed this! Read, review, follow, let me know what I can do better.

Edit: 4/30/16. This is just me tweaking some of the grammar and the structure of the story, the second chapter may be up by tomorrow, I'll try to get out a chapter of this a week, maybe two. Expect Friday/Saturday updates, or Friday/Sunday.

Have an enjoyable experience,

Anna.
