Based upon MOD's proven ability effectively conduct an acquisition process....I would bet Marly is right in his forecast.
The British ego shall not allow them to buy Blackhawks and go with a proven design that would have commonality with NATO allies.
Even if they do go for Blackhawks....it will be a bastardized version hawked by AW supporters.....rather than. buy off the s shelf from Sikorsky.
All you have to do.is look to past procurements of the Chinook and Apache.
