I think T129 will be unavailable to PAA until Turks have an alternative engine. If US is OK to supply Pakistan with the zulus, they will actively discourage engines for T129.But having 12 vipers doesn't make sence?either procure more and make reasonable number along Z10ME that's only way PAA exit the T129
We have the approvals, only sticking point is financing.
US used similar tactics in the 90s with South African Rooivalk was coming up. It was an awesome dedicated gunship platform built by the South Africans using Puma as foundation. However they lacked a good long range anti tank missile at that time. US prohibited integrating Hellfire integration with the platform as it directly competed with Apaches at a much lower cost. By the time Denel developed Mokopa, customers had moved on to Apaches or Tigers for their anti tank helo needs.
So for us it will be either AH-1Zs or Z-10MEs in the near future. I don't see an alternative engine for T129 for the next 2 years min.
