I am comfortable with most of this. I would like to see a production Taranis in service asap. But when you start to increase the size, cost will go up and you defeat the point of them.
The saving on pilot weight and kit is a small percentage, and if you are just doing this to avoid a few pilots lives, although hard the last 10 years would not support the case (how many pilots lost v soldiers on the ground).
the UCAV is not as such going to be cheaper than the equivilant manned plane. The F35 is a completely different capability if you try and match a UCAV with F35 capability, it will be very expensive. This is my convern as soon as I hear talk about fitting EJ200, how long before saying lets go afterburn and why not fit two?
1. No, you need to increase the size to enable it to have enough range, with a big enough payload, for the job it's meant for, i.e. deep strike.
2. Pilot weight & kit is a small percentage of a large aircraft, but it's a significant percentage of a small aircraft, such as Taranis. There are reasons other than saving the lives of pilots. A pilot can't remain effective in a cockpit for the length of time a UAV can remain airborne.
3. A UAV
is cheaper than a manned aircraft of equivalent performance, because the things needed to keep the pilot alive, & feed him information, are expensive. Some of that cost is offloaded onto ground systems, of course.
4. Who's talking about an F-35 equivalent? The Taranis successor is meant to be for strike or recce, not air defence or the other things an F-35 can do. All that guff about going from one non-afterburning EJ200 to two with burners is just that, guff. Jaguar wasn't reinvented to build a Hawk with two afterburning Adours, AMX didn't grow into something with two afterburning Speys, etc., etc. In both cases, the aircraft size was fitted to its role, & the engine picked to power that size. That's what is planned here, & there's no reason to imagine anything else.
