Army to procure 4 attack helicopter and BAF to procure 8. So, it is totally 12.
Army's requirment wasn't heavy helos in the first place. That is exclusively BAF's requirment.
T129 phase 2 is superior to older A129.
When the tender was floated probably back in 2021, the T-129 did not meet all the requirements as far as I remember, making its chances very low compared to the Mi-28, Apache, and the most expected one AH-1z. But the equation changed after the war last year. BAF's helicopters aren't also coming anytime soon, especially after selecting the Mi-28 just prior to the war and recently after the request for the immediate air support requirement from BD after European forces will be pulling out of Mali.
The funny thing is, the BA tender was for only 3 helicopters initially, and now we see 4.
BTW, I was trying to say the BD armed forces are already familiar with the AW helicopters similar to the Russian Mi helos and also more AW are coming, not to mention the company is well established, partnered with a local company, and already has contracts. AW249 looks promising too.
