Iraq's previous experience with CH-4 is very good, according them, CH-4 have conducted 100+ strike missions with 200+ attacks and 95% hit accuracy, this is better than the much more expensive US-made UAV's 90% hit accuracy.

CH-4 is a smaller UAV, with roughly 30 hours' cruise time and 200 kg payload.

CH-5 is a much upgraded UAV, with 60 hours' cruise time and 900kg payload.

Both CH-4/5 are entire built for exportation purpose.

The performance of CH-4 is also one key reason Iraq DoD placed another $2.5 billion order to China for VT-4 tanks and HQ-9 SAM last year.
