(inb4 the "not to rain on your parade..." posts, hehe... much less stressful now that there's something to speculatively be optimistic about, glass half full and all that... watching Phil mil modernization can be such an exercise in teeth-gnashing and hair-pulling eh, lol...)

here's an option that might brighten things up...

in the original US NAVAIR & Army PGSS (persistent ground surveillance system) program there were two main contractors for the aerostats: TCOM (which supplied the 28M aerostat the PN got), as well as Raven Aerostar...

now Raven also happens to own Vista Research (http://ravenaerostar.com/vista/history-vista), which specializes in the manufacture of backend radar signal processors which take the raw output signal from regular commercial marine radars and applies signal processing to provide more advanced target detection & tracking capabilities...

so Vista can take a typical commercial marine radar (like for example a furuno) and integrate that to it's SSRS (smart sensor radar system) to give products like it's F25 and F50 series (http://ravenaerostar.com/products/vista-research/ssrs-f25, http://ravenaerostar.com/products/vista-research/ssrs-f50)...

so maybe the TCOM 28M aerostat the PN got might have it's marine radar antenna and frontend connected to a Vista SSRS backend for the signal processing... now that would make it much better :)

^just from the shape and profile of the antenna @chief... that oval shaped end-cap profile is something the FAR X-band radiators/antennas have that makes them familiar in the 2000-series family of furunos...

yup, like @lion ^said... I was hoping for more but was expecting furuno, so yeah "ah well"...

5
^looks like they stuck a regular Furuno FAR marine radar onto it... ah well...

1st Flight-III ship procurement pushed to fy17 with Huntington Ingalls set to build the first in class ship (previously Bath Iron Works was slated to build the first ship to be procured in fy16)...

The Navy has reached a tentative agreement with Huntington Ingalls Industries for the shipbuilder to build the first Flight III Arleigh Burke guided-missile destroyer (DDG-51) in its Mississippi yard, the Navy’s acting acquisition chief Allison Stiller told a House Armed Services panel last week.
...
“We have a handshake agreement with Huntington Ingalls to introduce the Flight III capability on their FY ’17 ship,” Stiller told the House Armed Services seapower and projection forces subcommittee in a May 24 hearing.

this will make for a rather interesting situation in terms of ship numbering as it was originally intended that the first Flight-III ship would be procured in fy16 and be numbered as DDG-127 (with the other two ships procured in fy16 being Flight-IIA ships numbered DDG-123 and DDG-124)...

now with this new development for Flight-III procurement in fy17, if a third ship is still procured in fy16 but in a Flight-IIA configuration then this would mean DDG-123, DDG-124, and DDG-127 would be Flight-IIA ships, while DDG-125 and DDG-126 would be Flight-III ships...

all this number-merry-go-round due to the way the USN's procurement system handles multi-year contract block buys (ie. 14 ships up to DDG-126 were already in the system prior to Congress allocating initial funding  for a third ship for fy16)... maybe fudging with their ERP software's database to renumber the ships is too much of a headache for them, but I really wish they'ld just "bump" the hull numbers downwards so it looks nice and neat, lol...

^ah the "infamous" photo that caused all the ruckus, it should be made into a meme with a caption that reads: "Hi hi hi", lol...

more teasers from the FB extension:

EL/M-2106NG transportable 3D short-range (100 km instrumented) radar at Wallace... this is the so-called "gap-filler" radar which was offered as part of the procurement contract for 3 units of the EL/M-2288 long-range radars...

here comes PAF into the modern era of 3D solid-state air-defense radars... about time :-) more good times ahead... (am not counting the "secretive, infamous, mercurial" AR-320 since that used a TWT power amplifier in it's transmitter, hence is not full solid-state)...


9
^ah ok, in that case, Thales does advertise that they can integrate their Topsky CNS/ATM into a military air defense system, so the potential is there...

10
^sorry @mayk, I don't have any public source info on that... maybe other forumers better connected to CAAP can answer that question...

the SPY-6(V) AMDR (Air and Missile Defense Radar) engineering and development model (EDM) prototype recently conducted a ballistic missile tracking test at the PMRF (Pacific Missile Range Facility) in Hawaii:

http://raytheon.mediaroom.com/2017-03-31-Raytheons-Air-Missile-Defense-Radar-successfully-executes-first-ballistic-missile-test

the AMDR is the next generation AESA radar which will equip the USN DDG-51 Flight III destroyers, and will provide a sensitivity which is nearly 32 times greater than the current SPY-1D(V) on Flight IIA ships... see this post for a discussion on the AMDR's capability...

I was watching a video on FF-16's patrol at Benham Rise (https://www.youtube.com/watch?v=ZV4Lkepv84c) and noticed the following in a segment where the camera was showing the Manta Digital multifunction display of the Kelvin Hughes navigation/surface-search radars of FF-16:



in the top, upper-left corner of the display you can see the following three lines:

Quote
X-Band Master
Tune
Pulse MP

when FF-16 was first acquired we know she was equipped with the Kelvin Hughes radars (which were a "step up" from the usual Furuno radars used by the PN) but it wasn't known whether she had the regular magnetron-based radars or the newer solid-state "SharpEye" radars which had two prominent advantages: (1) pulse compression giving better range performance, sensitivity, range resolution, and clutter rejection; and (2) doppler processing giving target velocity discrimination...

now from the video clip shown above, the two menu display items: "Tune" and "Pulse MP" are features of magnetron-based radars and not solid-state SharpEye radars:

"Tune" is used to allow user-controlled fine variation of the magnetron frequency to avoid interference from other navigation radars... in contrast to this, "fine-tuning" is not used with SharpEye radars, which instead have pre-set selectable frequency choices generated by the solid-state transmitter... SharpEye will also transmit secondary pulses on a secondary frequency automatically selected as part of it's clutter rejection techniques, hence the user does _not_ fine tune the frequencies to be used by the solid-state transmitter...

"Pulse MP" indicates the medium pulse length setting which is one of three possible user-selectable choices (ie. short, medium, long pulse length) used by magnetron radars to set the length of all pulses transmitted... in contrast to this, SharpEye solid-state radars transmit frames of 3-pulses with a short, medium, and long pulse length in each frame with those lengths automatically set by the transmitter... SharpEye uses these 3-pulse frame transmissions to achieve it's better range performance and range resolution (via pulse compression) while still maintaining a low minimum range...

so from what was in the video clip it seems FF-16's X-band radar is still a magnetron-based Kelvin Hughes radar... hopefully her S-band radar is the better spec SharpEye solid-state type...

^nice find @Aris :D  they even showed some screen displays from CAAP's new Thales TopSky system...

Bath Iron Works (BIW) first Flight IIA restart ship DDG-115 "Rafael Peralta" delivers to Navy:

The first Bath Iron Works restart Arleigh Burke guided missile destroyer Rafael Peralta (DDG-115) delivers to the Navy last week, the service announced on Monday.

Peralta is the second of the restart Burkes – following the delivery of John Finn (DDG-113) Ingalls Shipbuilding — and the first from General Dynamics Bath Iron Works.

in the "teaser" pic posted by "Luis Machochito" in the timawa fb extension as shown a few posts above, one will note the similarity of the airspace monitor display to the following image from PAF's "ADW Journal (Sep 2013)":

(this image was taken from one of the ADW air defense exercises - ADEX)
