Information on the OLIVER HAZARD PERRY- FFG7

is it the 700 ingrham?  that kit has the option for either flight deck, the white lines are decals, but there is only one option, it doesn't provide for both landing grid lines iirc, and also has two types of choppers in it. 

edit:  i reread, it's the ffg7, sorry, i think it has both, i'll have to check my kit of the perry when i gets home.  i think they are the same molds though, so it may have both.

Short-hulled Perrys operated with SH-2 Seasprite helicopters.

Long-hulled Perrys operated with SH-60 Seahawks.   

Seasprites are smaller than the Seahawks and lack the LAMPS interface with the controlling ship.

The Dragon Ingraham does not include a Seasprite.    What John @ WEM was probably telling was that if you are modeling a short-hulled Perry, for accuracy sake you should not put a SH-60 on the flight deck.

The kit is of the Ingraham FFG-61,  last of the class.   It is a long-hull

As far as PE,  are you sure you were checking on the 1:700 scale Perry set from WEM.   Their 1:350 scale set is beautiful,   but their current catalog doesn't show a corresponding set in 1:700.

dragon put out two perry class in 700 scale.  the ohp and the ingraham.  i've got both kits and just checked them.  they are identical except the decal sheets and the ingraham has it's own pe set included.  they both have options for the short or long hull, it's just a different peice, either 55 or 61 as you choose. the flight deck is attached to the upper hull in the mold.  i don't know what the helos are that are included, but there are two different types in each kit.

hope that helps a bit more.
