I have been scanning some old slides and came across some slides of the Yf-17that were being thrown in the trash when the F-18L was cancelled. They show some demonstration weapons loadouts for F-18A development. The earlier ones with the aircraft in silver paint are from 1975 while the camo paint is from March 1976. Here are the 1975 images

Thank goodness you had the fortitude to retrieve them BillRo!!

Every now and again for several years I presented the F-18 mockup to visitors to Northrop. Here are a couple of pix with the big models we used to explain the aircraft. They did not let me talk to the possible customers, but the guy with me in the dark photo was the Brit Consul General in LA.

Thanks Bill - nice model.

Wow, 50-years.....so that means I was 3-years old when she first flew.

Although my experience with the Hornet isn't as exciting as BillRo's [I'm very envious Bill!], this anniversary gives me cause to reflect....
For in 1986 whilst at school I applied and sat exams for apprenticeships in building the Hornet at Fishmans Bend in Port Melbourne. Alas no apprenticeship, but a great and exciting life experience just the same.
On reflection, as a Digger, I've seen her grace in many a take off and landings, I've witnessed her sheer power of and manoeuvrability over airbases, I've sat in awe of her cockpit, I've helped protect air base from which she's operated and I've seen her deliver ordance.

I guess my only regret on reflection is that no F-18L / F/A-18L ever entered service.

The rollout ceremony book was my first EBay buy what, 20 years ago - neat to see it elsewhere!

A well put together video regarding the LWF/ACF Competition, which includes an interesting snippet in regards Northrops P-610 single-engine study at Time 21:29, denoting both the weighting saving of the single-engine derivative, as well as that the PP-610from a Northrop perspective would have had a more promising manoeuvrability than the two-engine P-600, which became the YF-17.

Interesting tit bit.

I wonder how the P-610 would have matured. For one, it doesn't seem like much thought has been given yet to the location of the nose gear so not have a major impact on intake performance in gear down conditions.

While promising, it is clear the P-600 was further developed and a bit more mature design at the time hence continuing with it.
