Straightline Aviation is likely to sell the 12 Lockheed LMH-1s that it ordered first, but there are a good half dozen closely competing designs for heavy lifting craft of this type. It will be interesting to know which PRL ultimately chooses for local trials given the interesting weather we have up here. There are variants being designed with lifting capacities of upwards of 181 metric tonnes or even a proposed 450 metric tonnes. That's a big boy!
