Maybe it is a modernization of Grad
More than just an upgrade when they change the vehicle chassis to a new truck.
I sense some disappointment from some members here that the system does not use palletized clusters of rockets.
Not so much disappointment, as confusion.
The previous set of photos showed the old truck with new systems/automation, the above set show a new truck with the old rocket setup.
The main reason I like the palletised rockets is because they can reduce the number of chassis types and have different rocket options for different vehicles.
The chassis above is the light vehicle that can replace Grad... it will be lighter and cheaper than the larger vehicle and will be able to operate with lighter units including on mountain paths and cross country that would bog down a heavier larger vehicle. The other advantage is low cost so while it can carry 122mm and 220mm and 300mm rockets it can operate is all sorts of terrain and can be afforded in larger numbers.
The other vehicle based on the trucks used by the Iskander family of ballistic and cruise missiles can replace the Uragan and Smerch with a wide choice of rockets.
THe lower cost of these vehicles to buy and to operate means they can afford to put them into service and still afford tube artillery as well... the latter can include 152mm, and 203mm guns and 120mm and 240mm mortars.
- Get both vehicles to reload: the crew of old system with fixed tubes will require 10 minutes of reloading time before firing again. The palletized system will probably need about the same amount of time to offload the used pallet and replace it with a fresh pallet. So, there is not much difference in firepower if the pallet is 40 rocket strong (in fact it contains only 30 rounds).
More importantly against a sophisticated enemy even if reloading took 3 minutes that would leave the battery vulnerable to counter battery fire. A more realistic procedure is to fire and then move and reload once you get to your new location. Even if it takes 20 minutes to reload after you arrive that doesn't matter because the meteorological unit needs to release a sounding balloon and track it with radar to determine wind speed at different altitudes before they can calculate aiming tables to work out where the guns need to aim to hit their next targets. The excellent range of Russian rockets means there are likely several batteries in range of the target so even when one is moving you will still have it on call for use.
For the smaller Grads, the pallets are actually a disadvantage.
With a crane fitted to the launch vehicle or the vehicle carrying replacement pallets by using pallets you can reduce the number of men in a battery... further reduced with automation of navigation and aiming etc.
Having rockets loaded into pallets means no problems with weather or dirt and faster loading.
Only in a COIN situation would you remain and continue to fire at the enemy.
Pallets are not a super solution, but they have some advantages... especially with the heavier rocket types.
