>>298722mmm. you're talking about the Samsung K-10 Thunder Ammunition resupply vehicle.
the stated resupply rate of the K-10 to the K-9 is 12 rounds per minute (i.e. 5 secs per round). meaning 4 minutes to refill the K-9 magazine, which holds 48 rounds.
the resupply time for the PzH2000, using men, not machine, in training is "less than 11 minutes". for 60 rounds (i.e. 11 secs/round).
> The K-9 is smaller than the PzH 2000 but it is lighter and hence moves faster and longer than the PzH 2000.weight? 46 tons (K-9) vs 55 tons (Pzh2000). same engine output (1000 hp).
dimensions? PzH2000 is 40cm shorter (length over gun), the same width, and 10cm lower.
stats? let's see:
67 km/h (K-9) vs 60 km/h (PzH2000)
360 km (K-9) vs 420 km (PzH2000) range
750mm (K-9) vs 1100mm (PzH2000) vertical obstacle
gun stats... virtually identical, except for the following:
burst rate: 3rds/15secs (K-9) vs 3rds/9secs (PzH2000)
movement-to-firing-time: 60secs (K-9) vs 30 secs (PzH2000)
and this is both stuff that's more important to mobile artillery than reloading time. reloading is done in a place save from counterbattery.
btw, the weight issue isn't an issue for the PzH2000 - there's also the "lightweight" 35-ton version, the AGM, with an identical turret and performance.
