In earl-mid 1990's both Newport News and Ingalls designed export designs for Frigates. Orginally competing to meet a requirement by UAE.

There is an artists impression in Janes defence weekly 15 January 1994 P24, that showed the Ingalls design...I have a veryu poor photo copy, does anyone have a chance to scan the orginal in and post it here?

Thanks in advance

There actually were 3 distinct Newport News FF-21 frigate designs, ranging from 125 meters down to corvette size.

Litton Ingalls had an entirely similar, but distinct family of vessels of which the Sa'ar V was the smallest member.

The first FF-21 design appeared in about 1991-92, and featured a 106.3 meter overall length with an overall full load displacment just under 3,000 tons. An article fully outlining this design appeared in the May, 1994 issue of Naval Engineers Journal.

To make things even more confusing, there appear to be two separate FF-21 variants listed in a Forecast International report from August, 1997 that detailed two further versions, a "light frigate" of 1,950 tons and a "heavy frigate" or 3,870 tons.

The report only illustrates the "light frigate:"



I still don't know what the larger, 125 meter "heavy" frigate looks like, but this should fill in some of the other details.

Is it just me, or does this proposal look VERY similar to the US-built Sa'ar-5 class frigate?

EDIT: Ha, Just read where TinWing said the Sa'ar-V was a member of this "family"..answers my question.

Not exactly. As TinWing said, the FF-21 was a Newport News design; Sa'ar V was part of the competing family of ships by Litton Ingalls.

The similarities are mostly down to having similar objectives and similar available technology. I'd bet both teams had access to the same RCS estimating tools, for example, which would explain why the signature reduction features look so much alike.
