Common here in Silicon Valley, used to mean a round of funding for a
startup.

'Tranche' is used to refer to groupings or production runs of fighter
aircraft.  Here's a reference from the Wikipedia entry for the Eurofighter:




Production is divided into three "tranches" (see table below) with an
incremental increase in capability with each tranche. Tranches are further
divided up into batches and blocks, eg the RAF's Tranche one twin seaters
are batch 1 T1s and batch 2 T1As.

An article in   has a headline referring also to Tranche 2 of the
Eurofighter:

Eurofighter Tranche 2 Provides Rare Comfort to Fighter Makers
(from http://tinyurl.com/334mtn )

I know from reading Aviation Week that it's not only used for European
fighters--I'm pretty sure I've seen it used in discussions of the production
of the American F-16.

It's apparently also used in finance (again, Wikipedia, here the entry for
'tranching'):




the word tranche (sometimes traunche) refers to one of several related
securitized bonds
<http://en.wikipedia.org/w/index.php?title=Securitized_bond&action=edit>
offered as part of the same deal. The word tranche is French
<http://en.wikipedia.org/wiki/French_language>  for slice; in the financial
sense of the word, each bond
<http://en.wikipedia.org/wiki/Bond_%28finance%29>  (¿tranche?) is a slice of
the deal's risk <http://en.wikipedia.org/wiki/Risk> . The legal documents
(see indenture <http://en.wikipedia.org/wiki/Indenture> ) usually refer to
the tranches as "classes" of notes identified by letter (e.g. the Class A,
Class B, Class C securities).

I don't have the time right now to do the real investigation, but I'm sure
others can pick this up and run with it...
