[MOC] [UCS] [Instructions] MC75 "Profundity" Star Cruiser

MC75 Profundity Star Cruiser MOC

 

Hey everyone! Just posting an update on my MC75 Profundity. My original version used some technic liftarm supports at the front of the ship that obscured the lower command fin and wasn't as attractive. After trying a bunch of options, I've settled on this design as a balance of structural support and appearance. It's probably slightly less stable than the first version due to having one fewer support point over a smaller base surface area, but the ship isn't really designed for swooshing anyway, so I'm pretty satisfied! I additionally made some parts changes to reduce rare part usage; the new version also cut maybe 150 bricks overall. I hope you like the changes!

Although there are a few different variants of the ship that showed up in Rise of Skywalker, this is the base design as seen on-screen in Rogue One, commanded by Admiral Raddus during the Battle of Scarif. Although Rogue One and some online images were used occasionally for scale/size reference, I mostly used the MC75 model from the board game Star Wars Armada for the design (a fantastic board game for anyone interested in strategy games).

Part count: 3,294 LEGO bricks

Dimensions: 32 in. L x 7 in. W x 15 in. H

The original version took about six months of off-and-on design work to finish in LDD. I spent another four months testing the new stand for the update. Stud.Io was resisting while the PDF instructions manual was generating, but it got there eventually. The Profundity is designed to-scale with LEGO's new ISD (#75252) as well as most other JD MOCs, including the MC80a Home One, MC80b Liberty, and MC30c. The height of the ship was a bit of a challenge, but in the end the tall stand turned out to be an advantage for mounting other Rebel ships. Both the Tantive IV and the Ghost are designs by LEGO (the Tantive from the new ISD, and the Ghost from the Star Wars advent calendar) modded only for attaching to the model. The Tantive can be placed docked inside the hangar bay, escaping the Profundity, or on it's own independent stand.

The MC75 star cruiser is a Mon Calamari city ship repurposed for combat with battleship-grade heavy armor and a large weapons collar encircling the main body of the ship. The most well-known MC75 was the Profundity, commanded by Admiral Raddus during the pivotal Battle of Scarif. Boasting twenty point-defense laser cannons, twelve broadside turbolasers, four heavy ion cannons, twelve proton torpedo launchers, and six tractor beam projectors, the MC75 was more versatile than the MC80 and easily adapted to varying engagement styles.

The most notable feature of the MC75 is an armored outrigger fin extending the bridge command pod below the ship, a design choice intended to evoke the appearance of predatory fish feared among the Mon Calamari. A smaller fin above the ship housed the transmission array and primary sensor clusters. The large docking bay within the ship's nose was capable of docking ships up to the size of small corvettes (notably the Tantive IV). Although the MC75 lacked prominently displayed engine housings, twelve Kuat Drive Yards Gemon-15 sublight ion drives hidden beneath the rear armor plating allowed the MC75 to match the cruising speed of starfighter escorts.

I tried to be as accurate as possible to the on-screen appearance of the MC75, but decided to sacrifice the grills in the sides of the forward weapons collar. Unfortunately the scale also prohibited adding the 8 smaller sublight engines in the rear of the ship. Clearly the model isn't a 'swoosher,' but overall it's remarkably sturdy! Honestly the test build went much smoother than expected, given the complex angles and the continued presence of gravity (haha).

It took about twelve hours to assemble using Stud.Io and making corrections/fixing errors; should be significantly less using the manual.

Thanks for looking - hope you like the design!

The cruiser is beautiful! And I love that you've made a point of including some smaller ships--showing off different models in relation to each other is the best part of having models at a specific scale, IMO. My one suggestion here would be that the advent calendar Ghost is about 30% larger than would be ideal at this scale (I know this because I wanted to display it with my UCS ISD and decided it was too big). Have you thought about using a design along the lines of this one, which is still very slightly too large but is at least within a stud of the optimal length?

Thanks for your praise! I like your version of the Ghost, very efficient use of parts. I actually tried out a few different designs for the Ghost at a more accurate scale; here's one of the first versions I made, I didn't save the later ones. I ended up ditching them though because using the version from LEGO's Advent calendar helped with recognition. I end up attracting a lot of SW fans that aren't big into LEGO, and I personally found it more exciting to have them recognize the Ghost right away and then go back notice it in Rogue One, as opposed to asking me what the ship was. Just a personal choice.

That is a great ship. I just have two questions. Firstly, is it to scale with 77904 nebulon-B and not including the instructions, how much would it cost to build?

Hi there! No to your first question. As noted, our ships are designed to scale with the 75252 Devastator, and because the 77904 Nebulon-B is not to scale with 75252, it also will not be to scale with the Profundity. It is to scale with our Nebulon-B, however. As for your second question, used parts were running $500 on Bricklink from 8 stores in the US and Canada (not including shipping or tax) last week. But our customer service always provides free estimates on parts costs if that's something you need.

Weirdly though, the Millennium Falcon in 77904 is to scale with 75252 and this Profundity, and not to the Nebulon-B it comes with.

Thank you for your response, it is certainly a great build, your nebulon-B design is magnificient too, as are the other rebel vehicles that come with it.

It seems to be one of those strange things Lego do from time to time
