They wont give a big order because that will shut the door for imports. They keep ordering in peacemeal batches hoping to get a few imports in between orders.
Watch HAL coming up with a detachable mission pod for the LUH like the Ka226 has, sending the import gang into a frenzy. Noooo overweight, nooo the Kamov's pod takes 0.0009 secs less to detach, noooo the LUH can't climb as fast as an apache.
