Amen, brother. I'm sure there were some interesting lessons to be had from flying a novel configuration...although to be fair, they had tunnel-tested and flown the V-173.
I checked the references i have on the XF5U. The props were supposed to be Hamilton Standard four bladed teetering, especially designed for the vehicle. They weren't ready by the time the prototype was rolled out, so it was equipped with F4U Hydromatic units. Turns out it was a very poor match and they couldn't fly it like that. While waiting for the props, Zimmerman did some redesign based on lessons learned while ground testing. the cockpit was redesigned, and he added a trailing edge surface between the verticals.

A Japanese start-up is to send spacecraft to the moon in a deal signed with Elon Musk's SpaceX, the Tokyo-based firm said Wednesday.

Private lunar exploration company ispace said it would blast a lander and rovers towards the moon on a SpaceX rocket on two separate missions.

The spaceware will first orbit the moon in mid-2020, followed by a moon landing attempt set for mid-2021.

It comes a week after SpaceX confirmed Japanese billionaire Yusaku Maezawa will be the first man to fly around the moon on a SpaceX rocket as early as 2023.

"We share the vision with SpaceX of enabling humans to live in space, so we're very glad they will join us in this first step of our journey," ispace CEO Takeshi Hakamada said in a statement.

Hakamada also told reporters the company chose SpaceX as it is "highly credible" and "capable".

SpaceX President Gwynne Shotwell said in a statement that the company is "proud to have been selected by ispace to launch their first lunar missions".

Hakamada said he could not reveal costs for lunar programmes.

The company has already collected nearly $95 million from investors.

ispace, which now has more than 60 employees, competed as one of five finalists in the Google Lunar XPrize, which offered $30 million in prizes but ended with no winner.
Not perhaps..the RG41 should have been the Ratel replacement, carrying forth Denels initial investment in Project Hoefyster.
We all now know the political and other "aspects" to the Patria selection, and the shenanigans regarding the sudden changes in the selection processes and times.

From Air International 7/1987,

here is the future hypothetical airliner aircraft with Rolls Royce RB-529 ContraFan engines.


Feel free to move the topic to any place.

This news has been out for a few days now - a IHS Janes article on the RG-41, that perhaps should have been the Ratel replacement instead of the winning Patria AMV, that has become the Badger.

I'm not sure why they are suddenly offering it now - some foreign interest I presume..?

Further to the TBO discussions; the "VDS" is probably a helicopter dunking sonar set.

My thought exactly.  Something like HELRAS or FLASH, both of which have already been repackaged for USV use.  They don't work like classical VDS; they require "sprint and dip" operations, like a helicopter.
Visual sizing comparison, from Rotor & Wing International.  Powerplant is a single AE 1107C;  quite a change from the V-247's predecessor, the PW200/55-powered Eagle Eye.
What are the smaller missiles on there? ???
