Thanks!

Why did some Regulus IIs have landing gear ?
As a missile, the Regulus is not supposed to land, and it's easier to launch it with a rocket booster.

Those Regulus II missiles were prototypes and pre-production missiles which the USN wanted to be reusable on the grounds that they were basically very expensive unmanned aircraft.

Just like the Navaho's X-10s.

Regulus I also came with landing gear (FTM - Fleet Training Missile) - have to check but would think the II would have been available with landing gear for the same reasons.

Enjoy the Day! Mark

Attachment 1: details of the 'trim vanes' ( canards ). Stabilised the missile on launch and reduced its landing speed by 30 mph during testing.

Attachment 2: details of the 150lb magnesium 'sugar scoop' air intake casting and its boundary splitter, manufactured by RH Osbrink.

Attachment 3: loading an R-II onto a C-124 using the bespoke dolly.

Attachment 4: first surface firing from AG-157 USS King County, 10 Dec 1958.

Attachment 5: the complicated and congested deck operations to prep an R-II for launch from Grayback. If I understand the images correctly, with the upgrade for R-II a new external launching ramp was installed between the two hangars that 'picked' a missile out of each hangar. Must have been hydrodynamically noisy.

Clearest shot I've found of Grayback's launcher. Appears to run on fore-aft track with points ( switch ) to enable it to roll into selected hangar. Additional lateral curving track to provide azimuth when launcher in aftmost position.

Also a bonus photo of the deck and hangars after conversion for SOF support. Mk VII SDV in port hangar. Some tracking still visible on deck.
