The Jerusalem Post, recently reported that plans to procure two new have been scraped.  It appears that two new 4.5s will be built instead.  The Meko,s would of been a major upgrade over current platforms.  However, I suspect that the two 4.5s will be a stop gap and further ships will be purchased in the next several years.  Here is the logic, once the gas fields come on line fully there is going to be a major revenue boost associated with sells to Europe.  The navy will likely see some benefit from this.  I wouldn't be surprised to see the Navy fielding two Meko,s in addition to the two 4.5s by the end of the decade.  This would place the Surface Fleet Inventory at Ten 4.5 Three 5.0 and Two Meko,s with Six Dolphins, excluding patrol boats of course.  I feel that this combination would be sufficient, to meet the Israeli needs as long as these levels were maintained.  Iran isn't a naval threat and the newer Type 214 being fielded in the next three years can handle Iran.  Turkey, Egypt, and Syria are a threat however, the Egyptian and Syrian navies are far from impressive from a technical standpoint.  Turkey has a navy twice the size of Israel however, once again theres a technical gap between the Turkish Frigates and the Missile Ships, this has been documented by US Military Commanders when Turkey was threating Israel with naval escorts to Gaza.  A Sar'r 5.0 has a weapon payload equivalent to most Destroyers and the 4.5s equivalent to most Frigates.
