Meir class DDG (Export version)
http://img38.exs.cx/img38/1442/DDG1417.jpg
OVERVIEW: IDF's new Meir class guided missile destroyer is a multi-purpose destroyer designed for stealth operations. It takes the stealth technologies built into the Farragat class and expands on them with newer innovations such as a trimarian hull. The ship is well armed and suited for escort duty or solo operations. It's RCS is less than 20% of an Arleigh Burke DDG's signature
SPECIFICATIONS FOR ISS GOLDA MEIR, DDG-1417
length: 548 feet
beam (overall) 120 feet
main hull beam 64 feet
starboard and port outrigger beams 22 feet each
beam of joints 6 feet each
draught: 24 feet
displacement: 11,750 tons
Powerplant: 5 IGE 5,600 gas-turbine engines (20,000 shp normal cruising each max rated at 25,000 shp for 12 hours)
Propulsion: 2 water jet propulsors
speed: 39.4 knots max sustained speed for 12 hours, 32 knots cruising speed
range: 7,500 miles at 20 knots
WEAPONS
1 x 5 in ETC gun
2 x 96 cell VLS systems (12x8) 1 bow and 1 aft
2 x quad round harpoon launchers
1 x 8 round ASROC launcher on the bow
2 x 18 in 3 tube launchers for Mk-54
4 x 30 mm Goalkeeper CIWS
3 x 10 round RAM launchers
RADAR
Basic IDF Aegis III package
Air Search/Fire Control: RCA SPY-1D, 3D (SPY-1D(V) phased arrays AEGIS
Surface Search: Norden SPS-67(V)3
Navigation: Raytheon SPS-64(V)9
Fire Control: 3 Raytheon RCA SPG-62
SONAR
Gould/Raytheon SQQ-89(V)10; combines SQS-53C bow mounted active search/attack with SQR-19B passive towed array
Countermeasures:
Prairie/Masker around propulsors and engine spaces
Nixies streamed from aft line
chaff canisters can be fired from the deck to confuse missiles
dropped torpedo decoys are available for both active and passive SONARs
Stealth technology
The prairie/masker system is just the beginning on this ship's stealth charicteristics. The bulk of it's abilities come from the hull design. The trimarian hull gives this ship a much smaller RCS than conventional hulls. The ship lacks any directly horizontal or vertical surfaces, this is shown by the upward pointing fore and after well decks. This also gives her a much smaller RCS. The superstructure has strange angles where a wide base angles into a fairly narrow bridge deck. The bow and after sides of the superstructure are also angled inwards from a longer base to a shorter top. There are many weird angles across the whole superstructure, and they are quite successful in masking the ship. The The steel hull is lined with a new plastic composite that absorbs active RADAR pulses. An Arleigh Burke DDG is said to be smaller than a fishing boat on RADAR, the Meir is 80% smaller on RADAR than the venerable Burkes.
Helos
There are 2 helicopter bays that can fit most ASW choppers. In IDF we use the SH-60I Seahawk
COSTS = $1.5 BILLION
NOTES ABOUT IDF'S DOMESTIC VERSION
The Domestic version has classified technologies that are not allowed for sale at this time. The RADAR system on the domestic is the new Aegis IV, which replaced the Aegis III as IDF's top system during last year's refits. The IDF version has LADAR for air search and fire control against stealth aircraft.
There are 144 VLS cells in 2 x 72 12 x 6 Mk.72 Freethinkers VLS cells. These of course aren't available for export as Freethinkers makes these cells.
The defensive systems are improved on the IDF version. In addition to the basic missile defense, there is 1 low powered lasers with a power output of 5 kJ. The laser's effective range is 150 miles. It can be refired every 5 seconds and works in conjunction with the standard missile. This laser is similar to the one that is being considered for usage on the 747 as an ABM system. It is actually shorter ranged than the 747 laser, but still has the power to kill an ASM. It may have the capabilities to kill aircraft, but only at much shorter ranges than it kills missiles.
