Re: Gearing-class NGFS Destroyer - late 1980s era |

Interesting for sure! The n the effort to make a 600 ship fleet while enlarging the NGFS capability, Rearmed Gearings and reactivation and uparmed Adams class DDGs would be great. I imagine that CONEX box enclosures for RPVs/UAVs on either side of the aft 5” gun leading to a fantail launch/recovery point would be pretty good.
A Charles armed with the NTU would give excellent counter battery fire While being able to calculate counter battery fire and begin the fire mission.

A follow-on might be an Adams class with the Mk-13 replaced.....lots of weight to add something fun there. Already had two MK42, ASROC...and we can look to the German hulls for FC mods. Forrest Sherman's would make a good baseline for close NGFS, easy to place a 76mm Oto forward where the 3"/50 twin was originally. Aft as well if you like I realize it is non-US, but we did already have a Gun deal with Oto Melara for their 76mm, so....The Italian Compatto 127mm/54 (Audace, De La Penne, Mastrele, Lupo classes) had a weight of only 42 tons empty, and had a 40 rpm rate and the ability to use US 5" rounds. Considering the 127/38 Twin the Gearings have weigh, this might make the higher rate of fire possible on less weight instead of adding 20 tons on each end by moving up to the Mk 42. http://www.navweaps.com/Weapons/WNIT_5-54_LW.php

Cliffy, Thanks for the weights! Cliffy B wrote: Missiles: Mk-16 ASROC "Pepper Box" = 23.9 tons

I had posted on SMARTROC before - a Paveway boosted by an ASROC rocket motor.
First version only went about 5nm (same as ASROC), but a second version with a customized booster hit 24000yd (12nm)
That was throwing a Mk 82, or 500lb, bomb.
CEP was 20ft, same as Paveway of the time.
Tests on the second version were 1975-78.
Ref: Sumrall, Sumner-Gearing Class Destroyers, 1995 Naval Institute press, pg 142.
This book also has data on the SOB program - Shrike On Board - where four Shrike Anti-Radar missiles were placed above the ASROC launcher for dealing with radars when on the gunline...

Re: Gearing-class NGFS Destroyer - late 1980s era |

@navydavesof, my concept is a multi-mission platform. The reason for the Harpoons forward is that the ASROC launcher would have the ability to fire Standard ARMs as well as ASROC similar to how a few of the Knox class were upgraded in the late 70s' before they were switched to Harpoon/ASROC. My other reason for the Harpoon placement is the placement on the Coronado LCS (I know not the best example:), but aft was taken by the MK-29, and the top of the hanger was taken by the countermeasures and ECM). I almost switched the Mk-29 and the Harpoon positions, but finally decided on keeping the MK-29 aft to improve flight operations and reduce flight deck limitations.
The large platforms for the CIWS was to get the guns higher so that they had more open range without hitting anything near by (such as the boat, or antennas). Additionally the raised platforms were enclosed giving space for additional reloads of ASROCs or Standard missiles (gives the ship a little more teeth). As for the SPS-49, yeah with the other improvements it would only make sense to upgrade the radar as well (I also included upgraded communications as well). If it wouldn't make her to heavy I would have added the SPS-48 as well, to give her the extra capabilities that adds since she is a bit of a "light" DDG having the Standard capabilities.
I know all the improvements would not be considered cost effective given the age of the Gearing's at the time, but that is the fun of "What-If" modeling. However, given the life many of the Gearing's had in other navies (when given further modernizations) the cost might have been worth it compared to new builds for lesser roles such as frigates.
I cannot wait to see your build, the MK 42 should make for a nice looking ship.

DJB,
Fascinating model! My version will be a bit different. I see you have a very large platform built up for the CIWS similar to that on the Iowas. The arrangement confuses me a little. What would the mission of this ship be?
What reaches out to me initially is the CIWS platform. I don't understand why to place them there or why to build such a big platform. The next is the Harpoon arrangement. Harpoons belong between the stacks and not ahead of the bridge. I agree with your idea of the SPS-49. That is a risky position, but because the Gyatt embarked it, it think it's a good idea!
I will not be embarking Sea Sparrow, instead I will be retaining the aft 5" position, with a Mk42 mount. Mk42 5"/54caliber and one Mk75 76mm gun is an excellent arrangement for surface warfare. The ASROC launcher could also be fitted with 750lb laser guided bombs propelled by an ASROC motor our to 15nm.

Back in the day there were at least 10 FRAM II Gearing DDs left in the mothball Fleet. They would have worked great.

When considering an introspective Navy with a solid funding line, I believe the Navy would go ahead with trying their Littoral Combat Ship theory with 2 or so ships stored in the mothball fleet. For instance, they could have pulled 2 FRAM II Gearing class DDs and fully modernized them to meet the mission areas. This would include the replacement of the twin 5"/38caliber guns with Mk42 5"/54s from decommissioned DLGs and CGs, installation of the Mk160 Mod1 GFCs, SPQ9A, RPVs, etc as described below:
Weapons: 2x Mk42 5"/54caliber guns in place of Mts 51 and 3. 1x 76mm gun in place of Mt52. 8x Harpoons amidships forward 8x ASROC/ROCGP 750lb laser guide bombs 2x Mk32 SVTT 2-3 CIWS
ECM: SLQ-32 SRBOC
Radar: SPS-49 SPS-10/55 TPQ-37 counter battery radar The hangar would be englarged along the portside of the aft stack to accommodate a single SH-60 and several Pioneer RPVs.

Rick, I may have miscommunicated. It is not my desire to add 3" guns but to instead say that I plan to hae Phalanx CIWS in place of the bridge wing 40mm/3-inch platforms. The way the CIWS would be driven is that the SPS-40, SPQ-9A, and the TAS-23 would be wrapped up together into one display by the SYS-2 integration system for CIC. That way, the system can react faster to threats emerging from the shore. Rick E Davis wrote: Were there operational Recon RPV drones in 1980-81? Not just yet. The first one was deployed aboard Iowa in 1984, so their testing stretched back maybe a year or so.

Not as sexy, but makes the exercise more interesting and a teaching effort on why this stuff wasn't done. Indeed. Thanks very much for your input!

Re: Gearing-class NGFS Destroyer - late 1980s era |

Dave,
None of the FRAM I or II GEARINGS retained the 3-in/50cal mounts after the upgrade. So if you desire to add 3-in guns, that would be extra weight. In that case "newer" versions maybe a better option. Not sure what 3-in guns were "off-the-shelf" in 1981, but the Mk 75 (OTO) 76-mm gun would be a likely choice. At most, mounting say two Mk 75 on the centerline would be the preferred option for gunfire support. But, if you are worried about Anti-Ship missiles, like Silkworm, maybe no or only one 3-in guns, with one CIWS.
Were there operational Recon RPV drones in 1980-81? I still think deleting or cutting down the DASH helo hangar, if it can't be used for other purposes (crew spaces, repair shops, etc?), is an option so the space can be freed for other purposes.
It is easy to go over weight and over the crew size that can be accommodated on these old hulls.
Think of an INTERIM capability until something newer can be built or converted, only fill a "gap" for five-ten years. The GEARINGs would need to be modified quickly to be useful out to say 1990. Most of what is onboard the GEARING FRAM I is still useful and maintainable, so think what can go and what can be plugged in without a development program or too serious modification effort.

Dave, here's some weights to help with the ideas.
Missiles: Mk-16 ASROC "Pepper Box" = 23.9 tons
Mk-141 Mod 1 Harpoon (4 tubes) = 6.5 tons (Fleet use) Mk-140 Mod 0 Harpoon (4 tubes) = 3.5 tons (Lightweight versions, found on PHMs)
Guns: Mk-15 Phalanx (Early models) = 6.25 tons Mk-15 Phalanx (Later models) = 6.8 tons
Mk-27 3"/50 Twin = 15.7 tons (Early model) Mk-33 3"/50 Twin = 16.2 tons (Later, improved model)
Mk-38 5"/38 Twin (Enclosed, base ring) = 47.85 tons (0.5" STS) Mk-16 5"/54 Single = 33 tons
BTW, you don't need to bother with SPS-55 unless you want to spend $$$. All of them already had SPS-10/67 and given the limited remaining life in these things, those would be just fine.

Do you expect a Gearing that's been deployed and worked as hard as most US combatants to still be seaworthy by the last 5 years or so, when GPS-guided Harpoons were first introduced? Maybe if the ships were used only as infrequently for local operations as the Taiwanese, but I don't see a globally-deployed vessel to last long enough to make it to 2011 and the Block II Harpoons.

Why not use what is already on the ship? Does the ship need the top of the line radar for only a few years of service in a more limited role? The FRAM I destroyers got a "top-of-the-line" radar/ECM suite in the 1960s and were still functional. Depending on the individual destroyer, they had air search SPS-29 or SPS-37 or SPS-40 (for fleet-wide diversity) along with the long served surface search SPS-10. Pretty much the same radars used on the SHERMAN and CHARLES F ADAMS classes in the 1980s.
