The 130mm B-13 Pattern 1936 was a weapons sytem mounted on Soviet destroyers. The weapon had excellent ballistic performance and was probably one of the best destroyer guns in service among the Great Powers in terms of surface combat. This high performance came at a logistical cost however. These guns had enormous barrel pressure and initial models had a barrel life of as little as 130 rounds. Some destroyers, the Project 1 leaders and Project 7/7Us, would need barrel changes before emptying their magazines. Deeper grooves solved this issue – the original had 1mm, and initial change to 1.95mm, and then a final change to 2.7mm. Whilst this solved the issue, this introduced a new logistical headache as range tables and ammunition were incompatible between the groove types. By 1941 however, the majority of the 378 guns in service were using the deepest groove. The 130mm B13 remained in production until 1954, with 1,199 mounts produced. Several were used as coastal battery mounts.

A project was in progress to lengthen the barrel to 55 calibres, called B2U, U standing for universal. The project was cancelled due to the start of the war, and were intended to be used on the next generation of destroyers.

The last series of destroyers this gun was used on was the Skory class, the first series designed and laid down after WW2. Several were exported to Egypt, Poland and Indonesia.

    Hi, I need resources for organizing IRL for once.

    My neighbor lives in the same gentrifier-building as me (think insanely expensive rent, worst renovations in the world, no maintenance). I've never talked to them before (we're super alienated from each other) but yesterday they came up to me and said they cannot pay the proposed rent increase and proposed organizing together. The increase is like... 50% on top of our current rent. Somewhat justified by the market but even then it's a stretch. The building has maybe 4 other units with tenants, plus several empty units.

    I thought tenant organizing was a fake thing for twitter leftists but here it is in my literal home. What the fuck do I do??

    First reaction was to knock on doors or maybe slip letters under people's doors. Is that a good start?

    Can someone share some resources? Thanks!

      The basis of all organizing is relationship building. If you can’t afford to live there with the price hike, you’ve got a few months at least before you could be properly evicted. Google tenant’s unions in your city or state. If you can connect with someone local who’s got experience organizing, that’s ideal. At the very least, their websites should have resources.

      If you have any communal areas where people hang out, going there to complain about the rent may be advisable, but less so if the landlord has cameras on that spot

        Thank you for this. Yeah we have a tenant's union, but I think they may have their hands full. I suppose I could offset their lack of resources by volunteering to organize :)

        That aside, our broker told us to ABSOLUTELY contact them if we had crazy rent increases (which they just about guaranteed would not happen). I do wanna make use of this resource, but I'm also concerned that if they smell any frustration that they may snitch on us to the landlords. Really not sure about the downsides/upsides to this.

        But moreover I need to get educated and look up my tenants rights, and to see if our landlords have been hiding any kind of existing rent control legislation in this building.

          Legit, send an email or message to the tenant’s union. Worst thing that happens is they don’t respond

            Yeah I'll do this. I need some basic guidance. I'll do all the heavy lifting anyway.

            Thanks comrade!
