Can it be upgraded to a BMP-2 or is the chassis too different?

    The chassis is the same, but to upgrade it to the BMP you'd be replacing pretty much everything else.

      Its not. BMP-2 has different hull.

      What even changed besides the turret?

      Larger and newly shaped hull. It looks the same, but it is not.

      >tfw I will never own a BMP-2
      it's my favorite vehicle. I would live in it if I could.

      I have been in many different soviet armored vehicles, including BMP-2. Its comfy.

          The BMP-2 is MORE cramped than the BMP-1, what are you smoking?

          Yes, because the larger turret

            Wouldn't replacing the turret with a HMG turret like mentioned before add alot of internal space?

              Not necessarily. Bmp-1 turret design wasn't great in terms of the gunners ability to do his job. The upgrade helped with that but the extra space had to come from somewhere

                I was thinking about this specific turret. It only has one guy, eliminates the autoloader baggage and has really good elevation since it is based on a AA mount..

                2x14.5mm with a 7.62x54 seems a significant improvement over the grom.

    The chassis are the same but you would have to enlarge the turret ring on the BMP-1 to accommodate the larger turret of the BMP-2

      That seems like something that has already been stamped out fifty million times and is sitting in a pile somewhere rusting.

          Maybe a simple google search can answer your stupid question:
          > The BMP-2 is broadly similar to the BMP-1. The most significant changes are:

          >The commander now sits with the gunner in an enlarged, two-man turret.
          >Armament changed to the 2A42 30 mm autocannon and the 9P135M ATGM launcher capable of firing SACLOS guided 9M111 "gayot" (AT-4 Spigot), 9M113 "Konkurs" (AT-5 Spandrel) and 9M113M "Konkurs-M" (AT-5B Spandrel B) anti-tank missiles.
          >Only seven troops can be carried instead of eight.
          >Two rear infantry roof hatches instead of four.
          >Slightly improved armour.

          > The BMP-1 and BMP-2 share the same chassis and have almost identical road performance. The BMP-2 is heavier, but also has a more powerful engine to compensate.
          > Its armor is slightly thinner than the BMP-1's but the higher-quality steel used in its construction grants it the same effective protection
          > The original BMP-1 had a vulnerability in its mine protection scheme, which only became obvious during the war in Afghanistan

          Before the Ukraine fiasco, there were companies selling surplus BMP-1 variants along other eastern bloc armor to the consumer market. Needless to say many of these businesses inventories have dwindled in 2014 and in the wake of 2022.
          Not the same as a BMP-2 but it’s the closest thing a rando civie can get his hands on.

    Given the lack of ergonomics of the bmps, recovering or capturing fricked hulls and the like, and the usefulness of lighter vehicles during mud season, has anyone tried to make a cvrt equivalent out of bmp parts? Like when your troop carrying capacity in negligent anyway because it's so uncomfortable that soldier ride on the top, you might as well make a smaller vehicle with better ergonomics with reduced transport capacity that soldiers will actually stay inside. Yes I know that's a scorp and can't carry troopers.

      I don't blame them from using what they have. But having the first wheels so close to the centre of the vehicle is a weakness vs land mines.

    Need to replace the entire roof and rearrange the inside.
    BMP-2 turret ring is much bigger which means it intersects with the commander’s hatch on BMP-1 and some of the cargo seats
    You can use a smaller BMD-2 or BTR-80A 30mm turret though. Ukraine made a few of the former while Russia produces the latter

      The BMP-2 turret ring is bigger, as a result the BMP-2 is an even worse cramped shitbox to ride in as a passenger.

      Can it be upgraded to a BMP-2 or is the chassis too different?

      Should just remove the turret, add a spacer and buy a bunch of those 2x14.5mm turrets the Norks put on everything. It would give it decent suppression capabilities as well as some vague AA ability.

    Doesn't the original BMP-1 have gas tanks inside of the rear door as well for some reason?

    • 3 weeks ago

      Yes but it's a bit of a meme.

      Diesel doesn't light that easily and ultimately you have to put the fuel somewhere in the fighting compartment.
      The passengers in the BMP also sit on top of a big fuel tank as well, but all IFVs have to find a solution for this problem.
      Some designs deliberately use fuel tanks as spaced armor to provide additional protection against HEAT charges, the Abrams has them on either side of the driver for this purpose to help protect the crew compartment from 20°-30° off angle hits.

      The bigger problem for the BMP in regards to crew survivability is it's small doors and cramped interior that makes it hard to get out of the vehicle.
      There are also loose high explosive rounds stored inside the turret basket that could explode sympathetically, although they are at least not caseless and somewhat inert.
      The low level of armor compared to many more modern western MBTs is not ideal either as a consequence of Amphibious capability and necessity of low cost to equip the sprawling Red army mechanised forces.

        Diesel lights very easily if it's being sprayed around by a nearby explosion. Those fuel tanks were meant to be empty when in combat, used only for long distance unit movements, just like the extra fuel barrels on the rear of T-72s

        • 3 weeks ago

          Losing the extra barrels on the tanks is probably more about allowing for full rearwards traverse of the gun than any particular safety reason.

          This is the center tank going up and spreading to the ammunition.
          At the end of the day you need to put fuel in the vehicle if you want it to go anywhere.

      That diesel lights since it gets warmed from recirc through the common rail. When it aerosols from the tank being rupturing by explosion or penetration that diesel is closer to gasoline in flammability than not.

      The patent for the turret the ukes are putting on their bmps. This is part of the myriad of signs that Ukraine was working towards being far more self-sufficient with its mic and doubling down on upgrading the frick out of their old shit.

    I really like the BMP-3, i think it's one of the few decent things the Russians did in the last decades.
    I think there was also a BMP-3M where they gave it better sights, FCS, Thermals and slapped frickhuge ERA bricks on it's sides.

    No, but you can give it similar weaponry

    Both russia and Ukraine have their own 30mm turret designs that fit, some of them also include ATGMs

    Theres also the more low-tech solution of putting a BMD-2 turret on it,the BMD-2 has a 30mm cannon and an ATGM

    At any rate a two person turret is out of the question
