Are those the older 3-inch guns? Those are effective to about 8km right?
More like 14km if Im not mistaken.

It also got a new radar too.  Looks like the ship just went through some type* of refurbishment.

Ah...That's good. The ship does look great. There have been a bunch of pictures of nice looking PN ships.

About the gun, I was just wondering what could possibly be substituted for it. Maybe a 3-box configuration for Penguins :D

Anyway - nice looking ship.

I really thought it was a 40mm gun

It carries those too but those are on the stern not the bow of the boat.

here she is, at HPN in relation to the news you posted:



 :shock:

Anyone know what those really large antennas on either side of the superstructure are?

The mast also appears to contain a pair of wind-vane/anemometers. Used for fire-control?

Ignorant land-lubber question . . . what's the story with the three radars?

The large one is the primary search radar (US SPS 53?). The other two are navigation radars with the new one (Furuno) I am guessing having a secondary search function in addition to navigation.  The two antennas on the side are the long range communications antennas (HF?) though I'll leave it to the others to tell us exactly what they are.  I myself am not sure what type.

Oh, one more thing.  The assumption is that all the radars work.  It could be that the newer radar replaces the other navigation radar but they never bothered to remove the other one.

May I share that Radars onboard commercial ships were usually 2 or 3 sets.
One is the long range Radar capable of acquiring targets of 60 to 100 miles, the other is the short range Radar capable of acquiring targets of 24 to 36 miles.

They may put also the newest type of Radar which is called Daytime Radar.

Most of Radars not more than 20 years old have built-in ARPA. The newest kind of Radar is interfaced with AIS.

At least 2 Radars is required for safe navigation since in normal situation, one Radar is usually switch on at evening especially on coastal navigation while the Radar is swithed-off.

When entering or leaving ports and navigating near coast especially at night, it is normal practice to use at least 2 Radars. One can be assigned for tracking targets and the other one for getting ship's position for navigation purposes.

Mr. F shared the following excellent summary of ARPA and AIS here:

Additional about AIS and ARPA













Informations given by AIS set :

1. Course and Speed of other vessel.
2. Last port and next port.
3. GRT, Cargo, and other infor shared by other vessels.

Information given by Radar.
1. Target's bearing and distance.

Information given by Radar with ARPA
1. Target's  bearing and distance.
2. Target's course and speed
3. CPA - Closes Point of approach of target
4. Time of CPA
5. Risk of Collision - with automatic alarm

  The two antennas on the side are the long range communications antennas (HF?) though I'll leave it to the others to tell us exactly what they are.  I myself am not sure what type.


just for fun, sir, as a former ham radio wannabe during the time prior to the reign of cellphones and internet (pls don't quote me on this since i am guessing and i haven't been aboard that ship nor know what are her commo system) 

...the large vertical antennas on the side are most probably for HF radios with an operating range that include the 40-meter band. may even be broadband. i can't remember the proper nomenclature for those being a landlubber and not concerned with signal interference from a nearby steel deck and superstructure  as well as not limited with deck space to lay out my dipole antennas... in the mast, she also got what appears to be VHF antennas  for frequency ranges that includes the 2-meter and 6-meter band... i can't see any UHF antennas, but antennas for this band is usually small anyway and may not be readily visible from that picture.
