The British system were called Rainbow Codes

https://en.wikipedia.org/wiki/Rainbow_Code

See this from the article:

"During WWII, British intelligence was able to glean details of new German technologies simply by considering their code names. For instance, when they began hearing of a new system known as Wotan, Reginald Victor Jones asked around and found that Wotan was a one-eyed god. Based on this, he guessed it was a radio navigation system using a single radio beam. This proved correct, and the Royal Air Force was able to quickly render it useless through jamming."

Read R.V. Jones book "Most secret* war" if this kind of war-engineering interests you.

* Pay attention to "most secret" rather than the ghastly Americanism "top secret"!

Probably “Project Phoenix”.

If you ask any project team to come up with a project name they will probably pick ‘Project Phoenix’.

Because all project work is reviving something that has been done before?

No dude because it’s a badass name. If it’s super cool you get to name it “Operation Dark Phoenix” which is even more badass.

No, because all new projects are on fire from the get go.

Because projects start in the smouldering ruins of as-is, and their business case is mythical (and if you want to rise in this environment you’d better be flame-retardant).

Because the product is mythical and it will all end in flames.

The Phoenix did not end in flames. It started in flames.

It’s immortal and cyclical. There is no beginning or end. Popular focus is obviously on one part of that cycle.

That or NexGen/NextGen.

Someone should do a study...

*Sigh*

...Telstra in Australia called the transition from its 3G network to 4G "Next-G".

Why is this suddenly so depressing lol ._.
