The CGHRD-1165 greatly improves upon the CGHRD-1065 (while continuing to deprecate the predecessors of the CGHRD-1065) and:

• suggests some possible technological advancements in radar technology and capabilities
• has an innovative topside boat bay amidships
• retains the Flag CIC
• retains inside-ship-skin torpedoes rooms
• has longitudinally-divided main engine rooms (for enhanced damage control)
• has 4 GTGS (1 forward, one in each main engine room, and one aft)
• gains an Air Conditioning plant (for a total of 6 ACs)
• has a multi-ring, multi-planar, multi-band bridge-mounted radar mast
  

What the first and last bits refer to is the mast plates/faces can rotate clockwise, counterclockwise, or twisth in both directions, independent of the ring above or below it. The 0-7 and 0-9 level rings angle from the horizon level and up, while the 0-8 and -10 level rings angle from the horizon level and down to the surface. (The weakness in this design is that a sufficiently large mine explosion might cripple surface search and EM-defense equipment at one single point of failure; salt spray can cause problems if proper flushing and lubrication are not performed.) However, having the radar planes this high up increases the surface search an air search volume because the height of eye (well, the greatest transceiver height of the upper-most ring) is increased for some of the line-of-sight emissions and receivers.

Also, the rings need not rotate to accomplish search functions unless it is decided to split the emissions or search dwells and receivers among planes on the same ring. This would at first seem to be reminiscent of a hybrid analog and phased array, rotating surface and air search radar set. However, in this application, more radar planes or faces are doing more and varied work than a single plane, rotating, phased array radar mount. It is expensive, but it can prove useful. Aas for the single point of failure concern, one test is being conducted: a rapidly-erecting/vertically-telescoping ballistic shroud/ring activated by compressed air encases the radar mast. As for shock damage, the rings are gymbal-mounted and isolated by rubber rings and shock-absorptive fluid systems which also dampen vibration from ship motion (forward, emergency crash-back, beam seas, high winds, and other controllable factors.

This would be useful for "deceptive emissions" purposes. The very high mounted twin designator/terminal guidance directors (fire control directors) are notional. If they are too heavy, they will not be mounted. ( Alternatively, the notional fire control directors could be replaced with special purpose optics, IR, EM, and other detectors or equipment.) Instead, the rotating ring of panels can be employed to control terminal guidance of the missiles.

Conversely, to a limited extent, the rings can be used to emit dwells of tightly-focused, pinpoint high-impact energy meant to burn through the circuitry of inbound missiles. A future version of the rings will incorporate tilt rods so that any ring planes may adjusted for increased surface or air volume search. this would operate in a manner similar to the controllable pitch propellers, except that the rings could be seen as the equivalent of "contra-rotating propellers". A possible advantage is that swarm attacks by missiles and aircraft ("smart" weapons, vs "dumb", or solid, no-chip weapons), the ring planes can be adjusted for elevation angle as well as for output by emission strenght and emission spectrum. This could be the equivalent of "phased spread-spectrum/multi-frequency jamming". This could be phased and discrete, simultaneously. 

(Alternatively, for ease of understanding, visualize a round tilting floor, moved up and down by pistons located at the perimeter, or by a cam that moves radially to cause the tilt. Now, imagine a perpendicular virtual wall that holds the sensors. Normally, this wall is perpendicular to the sea except when the ship is rolling or pitching, creating a 3-D motion. If the ship is sailing along in calm, flat seas, the sensors might intermittently lose detection of small, stealthy craft at the edge of the sensors' passive or even active detection range. By tilting the sensors so the search plane is adjusted according to the range, more contacts may be detected.)









ABBREVIATED COMMENTS

WEAPONRY

As for weaponry, immediately noticable aboard the CHGRD-1165 is not the 155-mm (about 6.1 inch)  gun but that it can be replaced by a 203.2 mm (8-inch) gun and that is because there is below-decks accommodation for the larger hoist and the extra shell requirements. Moreover, even more valuable than a single 203 mm gun are the the four (4) additional guns mounts. These locations can mount  guns in the 37-80 mm range. This design attribute takes into consideration that some Asian operators may prefer guns to missiles for certain rules of engagement, particularly in and around the Strait of Hormuz, Indian Ocean, South China Sea, Strait of Malacca, Sea of Japan, Taiwan Straits, and other places where shipping traffic is high and pirate craft size is small, and where missiles would be "escalatory" (should it turn out that an UNAUN ship inadvertently sinks or severely damages the wrong ship with a single missile), expensive, and quite an overkill to convince a craft of interest to heave to and prepare to boarded for inspection. Also, the CHGRD-1165 employs the GoalKeeper anti-missile gatling gun for last-ditch close-in defense work as well as for selective close-in strafing. This ship has a sophisticated close-quarters, neutral-waters engagement mode that the USS Cole either had but didn't engage (a chain-of-command (ship 's CO  on up to TF/Administrative Admiral) political decision to please the locals in Aden), or was sorely missing (another political decision, but to please the locals stateside who were keen to obtain contracts to build woefully inadequate (humand and) Bushmaster guns. Ironically, the GE Phalanx gatling gun was designed almost from the very beginning to engage and destroy any and everything from aircraft, to missiles, to surface targets and high-speed boats to dolphins near the surface, but the Cole's CIWS guns were either "off", or were lacking the software patches. Basically, in the CGHRD-1165, the engagement mode considers:

• locale
• political tension
• previous court cases/engagement judgements
• sea state and wind conditions
• ship movement, course, direction, speed
• inbound air, surface and shallow-depth craft and mammals appearing to be  hostile
• relative closure rates between own ship and inbound objects
• in bound object course, distance, speed, maneuvering
• target response (or lack thereof) to automated hails by the CISW communications/interrogator
• thermal, IR, acoustical and magnetic propreties of the craft approaching the vessel

There are three modes of operation: Strafe-and-suppress; Dual Strafing; Berserk Nunchaku (aka "Chop Shop" or "Ship Chop" mode):




Delivering 3,000 rounds of DU or Tungsten along from either gun (worse if from both) should be enough to give a new definition to and appreciation for "survival/retreat mode" to any ship visited upon by CISW. It needen't punch through to the centerline, just grate the hull and frames to the point the target may be structurally unable to achieve high speeds in rough seas or perform wild evasive maneuvering. CISW is also ideal for ravaging a target's bridge, gun emplacements, gas turbine uptakes/exhaust stacks (does nasty things to air intake and exhaust ratios), bow, and stern. A bow-saw operation would upset the flow dynamics of an expensive destroyer or cruiser. A stern-saw operation would leave a target unable to propel or maneuver herself unless she has APUs which were left untargetted by local command override of the CISW. (CISW gun magazines carry a minmum of 10,000 rounds each.)


HULL


This hull also incorporates fin stabilizers/destabilizers (not reflected on the images on this site, but on the hull at Frame 346). However, only "fins" are aft of the amidships section. But, unlike the CGHRD-1065, this after set of fins is retractable. These plans reflect an interest in the fixed-pitch, swing-out fins, but a ship alteration may result in some or all the ships of this class being fitted with adjustable pitch fins non-swing-out fins. Since there are no fins forward, pitch and roll control are managed by ducted, angled (more longitudinal than athwartship, more vertical than horizontal) tubes (not reflected on the images on this site, but on the hull at Frame 160) that work to pull or push this ship forward of her turn axis or pivot point. In conjunction with the after fins, the ship can achieve or perform some "wild maneuvering" for a number of reasons such as:

• avoiding collisions
• deceiving or breaking lock of inbound missiles
• reorienting herself to take destructive fire at other areas of the ship to protect weakened or damaged areas (not just the surface, but also the below-waterline areas)
• flood and counterflooding (in this application, the ship need not be moving)
  
• last-ditch torpedo evasion (if the mains are for some reason off the line, these forward ducted thrusters can boost the yaw so the train of the APUs need not be exaggerated)
  
• long-range torpedo seduction/deception (by keeping distance, but changing own noise by running on a quieter plant -- assuming the torpedo logic prevents it from chasing sail boats in a seas near its primary target..)
  

The ship's three (3) APUs (Auxiliary Propulsion Units) are retractable. They assist with docking and mooring, station-keeping, creep-home, stealth cruising in search mode, and a few other activities such as when the GTGS power mode is desirable over GTM fuel consumption mode.

On the transom (at the very stern and below the waterline) are two independently-positioned fuel economizing and pitch-dampening flaps which impede the complete outward flow of water thrust astern by the propellers. (These are angled by  external hull-mounted rams or actuators positioned nearly-vertically, something considered in the design stage of the CGHRD-1165.)


But, in the CHGRD-1165, aside from dampening the stern vertical travel and smoothing out the stern rise and pitch, these flaps serve a minor role in disrupting the wake acoustics. They also play a small "backup" role (if needed) by imparting a slight heeling (without any intended roll or oscilation) to change the ship's aspect angle/ image in the search cone of an inbound misisle or aircraft detection set. (This is in contrast to the method used in the CGHRD-1065, which achieves this via use of the tactical computer which would control the 4 independent, active fin stabilizers when switching between stabilizer (smoothing), destabilizer (violent and erattic), and heel (graduated deception) modes.)

Plan, top, amidships (note the small-caliber gun mounts which are useful for close-up defense work; the split after VLM, which affords a centerline passageway on the main deck to permit each torpedo room to share the rounds from the opposite side (the torpedo magazines also support the helicopters); note the clear amidships area-- the boat bay is beneath the after stack, and it has port and starboard lifting doors which allow the gantry unit to deploy boats to either side, singly or simultaneously  ):






Plan, top, aft (note the flight deck and the cut-out/pocket aft- it affords mooring the ship even when moving a helo might be needed; affords a safer observation vantage point during flight ops; note the four traversal tracks--yes, there is room for FOUR helos-- two up to CH-46 size and 2 of the SH-2F, or OH-58D types):



Forward deckhouse, on the 01 level is the FLAG TOEC (Tactical Operations and Engagement Center) --UNAUN has not "CIC" since UNAUN is a maritime defensive/escort/police organization, not an expeditionary or flag-waving outfit; the two round units are the armored Sea Linux Command and Control data trunks, which extend from the bridge navigation table down to the next few decks, outside of the ships main TOEC, on deck 2.
