Mmm, look at that sweet, sweet bore alignment from the breechface to the suppressor end cap.
Regardless of whether you call them silencers, suppressors or mufflers, these Class III sound moderators have never been more popular but come with their own host of special considerations to keep them plugging along.
In addition to regular care and maintenance, you want to make sure you have a good bore alignment with your can– because a baffle strike can ruin your whole day.
According to the Russian Navy, they have been really involved in counter-pirate ops the past decade, with some years being more involved than others:
Since 2008, Navy ships have carried out 32 trips to the Gulf of Aden and other pirate destinations, escorting 152 convoys and 727 ships (56 ships under the Russian flag).
Ten attempts were also prevented, seven boats and 80 Pirates were detained. In addition to the Gulf of Aden, Russian military vessels have conducted anti-pirate patrols in the Singapore and Malacca Straits, South China and the Caribbean Sea.
The Russians also seem to be fans of breaking lots of eggs, no matter how small the omelet.
On the night of October 27-28, 1965 Viet Cong forces launched an attack on a newly built helicopter facility at Marble Mountain, southeast of Da Nang, RVN.

Here we see the Barnegat-class seaplane tender, converted to a floating command ship, USS Duxbury Bay (AVP-38), illuminated at night during a two-day visit to Basra, Iraq, as Middle East Force flagship in December 1960. You start life wanting to refuel PBYs and end up bobbing around the Persian Gulf for years…
The 41 Barnegats were 2,500-ton, 311-foot long-armed auxiliaries capable of floating in 12 feet of water. They had room for not only seaplane stores but also 150 aviators and aircrew. Their diesel suite wasn’t fast, but they could travel 8,000 miles at 15.6 knots. Originally designed for two 5-inch/38-caliber guns, this could be doubled if needed (and often was) which complemented a decent AAA armament helped by radar and even depth charges and sonar for busting subs.
All pretty sweet for an auxiliary.
The subject of our story, USS Duxbury Bay, is named for a popular 3-mile long bay on the coast of Massachusetts between Duxbury Beach on the east, Saquish Neck on the southeast, and the mainland on the west. The bay is also home to a maritime school that currently cycles through some 2,000 young mariners per year, so there’s that.
Laid down at the Lake Washington Shipyards, in Houghton, Washington, she was a fine craft easily mistaken for a destroyer escort or patrol frigate, as exhibited by these pre-commissioning builder’s photos:

Commissioned on New Year’s Eve, 1944, she sailed for the war in the Pacific, arriving to support the 3rd Fleet at Kerama Retto off Okinawa, 26 April 1945, and fought in the campaign for that island through June, tending both seaplanes and small craft/PT-boats when needed while dodging kamikazes.
In July, Duxbury Bay shifted to Japanese home waters before ending the war off China. She served on occupation duty in the Far East through 13 July 1948, with two short breaks stateside, supporting patrol squadrons at Okinawa and Yokosuka, Japan; Jinsen, Korea; Shanghai and Tsingtao, China; before the victory of the Communists under Mao brought a general evacuation from the latter area.
In all, Duxbury earned two battle stars for World War II service and suffered no damage, the latter an accomplishment for any ship.
Starting 17 March 1949, she left Long Beach, California on a five-month circumnavigation sailing through the Pacific and Med to Norfolk, where she arrived in time for the Independence Day holiday.
While on this trip, she tagged in as the flagship of Task Force 126, the small body of U.S. warships and auxiliaries in the Middle East, primarily in the Persian Gulf.
During WWII, the so-called “Persian Corridor” was a vital route through Iran into Soviet Azerbaijan that the Allies used to pump over 4 million tons of Lend-Lease supplies through to the East Front– and turn Tehran away from Axis influence. While the Persian Gulf Command sunsetted in late 1945, TF 126 kept the lights on for the Navy in the increasingly important part of the globe.
Duxbury Bay would see much more of the region.

Beginning in 1950, the Navy disestablished TF 126 and replaced it with the Middle East Force, which would be made up of two rotating destroyers and a dedicated flagship, which would also rotate. The three command ships for the MEF were all converted Barnegat-class ships: USS Valcour (AVP-55), USS Greenwich Bay (AVP-41), and our very own Duxbury— the oldest of the lot and the only one of the trio that had seen overseas WWII service.
Among the conversions done to the vessels were the installation of air conditioning and extensive canvas awnings over the decks, a white paint job to help reflect heat and show their status as “peace boats” (which earned them the title of the “Little White Fleet” a play on Teddy Roosevelt’s “Great White Fleet”), more commo gear, and a reduction in armament.
In general, the three flagships would swap out every four months and conduct leisurely cruises back and forth through the Med, waving the flag everywhere they went. As time went by, they became very active in President Eisenhower’s People-to-People program, delivering humanitarian aid ranging from food to coloring books and sewing machines in small backwater ports throughout the region– remember, as long as the harbor was at least 12 feet deep, they were good-to-go, and they went!
They served not only as a task group commander, interacting with Western allies (they were familiar sights at HMS Jufair, the Royal Navy base in Bahrain and its counterpart, HMS Sheba in Aden) but as a growing diplomatic tool for the State Department and U.S. companies (think=oil) looking to do business in the region, hosting state visits from local leaders and royalty (Duxford herself carried Ethiopian Emperor Haile Selassie to Somaliland in 1953).
The ships performed search-and-rescue missions for lost aviators and overdue boats, helped evac Western civilians in times of tension, served on the periphery of the 1956 Suez Crisis (which sent rotating MEF ships around the Cape of Good Hope rather than through the Med), and just generally served as modern station ships, a throwback to the old 19th-century practice of gunboat diplomacy.

In all, Duxbury Bay served 15 tours of duty in the Persian Gulf, the Arabian Sea, and the Indian Ocean as flagship for ComMidEastFor between 1950 and 1966, plus her original stint with TF 126.
While on stateside “downtime” at Norfolk, she participated in the Cuban Missile Crisis, refueled the occasional seaplane, helped run UDTs and amphibious training out of Little Creek, and was on the USS Kearsarge battle group that plucked Maj. Gordon Cooper’s “Faith 7,” the last Mercury space mission, out of the Atlantic on 16 May 1963 after 22 orbits.

After 15 rotations, it was decided to move to a more permanent forward-deployed flag and two of the three members of the LWF were pulled from service.

Duxbury Bay was decommissioned on 30 April 1966, and stricken from the Naval Vessel Register the next day. Both Duxberry and Greenwich Bay were sold for scrapping in July 1967, with just over 20~ years of service on their hulls.
Of their sisters, many endured for a good while longer than Duxbury.
These hardy seaplane tenders gave yeoman service to the Coast Guard and Navy through the Vietnam conflict. The last member of the LWF, Valcour, remained as the standalone forward-deployed flag for the Middle East Force, dubbed AGF-1 until she was relieved by USS La Salle (AGF-3) in 1972. Valcour went to the scrappers herself in 1977.
A total of 18 Barnegats transferred to Coast Guard in the 50s and 60s to become the “Casco” or “311” class (for their length) of heavy weather endurance cutters, WHEC, with pennant numbers 370 to 387. Many were renamed traditional USCG names, e.g after past Treasury Department Secretaries. Many of these were subsequently transferred a second time to overseas allies such as the Republic of Vietnam and the Philippines.
The last of the Barnegat afloat was the USS Chincoteague/Ly Thuong Kiet/Andres Bonifacio, a veteran of the U.S. Navy, Coast Guard, South Vietnamese, and Philippine navies that were finally withdrawn from frontline service with the latter in 1993. She endured another decade as a pierside hulk used for the occasional training until she was sent to the breakers in 2003.
The closest thing to a monument for these vessels is the USS/USCGC Unimak (AVP-31/WAVP/WHEC/WTR-379), the last of the class in U.S. service, which was sunk in 1988 as an artificial reef off the Virginia coast in 150 feet of water after three years with the Navy and 40 with the Coasties.
For their part, veterans from our ship visit Duxbury Bay in Mass often and hold ceremonies to remember their vessel.
As for the Middle East Force, it grew into CENTCOM in 1983, with the Navy contingent labeled United States Naval Forces Central Command (USNAVCENT) of course, and it is quite a bit larger than three little white seaplane tenders.

A report compiled twice per decade by the U.S. Fish and Wildlife Service shows increases nationally in wildlife watching and fishing, but declines in the number of hunters.
The survey, the 13th conducted by the USFWS since 1955, showed marked increases in the numbers of Americans engaged in observing and photographing wildlife and in fishing when compared to the 2011 data, but over the past decade, the number of hunters has dropped by more than 1 million– even as the general population is on the rise.

Speaking of bazookas, the Army just approved 1,111 M3E1 84mm recoilless rifles for immediate use as a lightweight (titanium) reusable replacement to the standard M3 Multi-Role Anti-Armor Anti-Personnel Weapon System (MMAAWS)– better known as the Carl Gustaf.

There are a lot of interesting things going on when it comes to GPS systems and their use.
The Global Positioning System (GPS), originally Navstar GPS, is operated and maintained by the U.S. Air Force and is a series of 24 satellites in orbit that helps find things down to about 5m. Set up in the late 1970s, China (BNSS), India (NAVIC), the EU (Galileo), Russia (GLONASS) and Japan (Zenith) have likewise set up their own systems to assist their own needs.
Long the gold standard for land and sea nav, GPS has replaced Loran and Omega systems as well as in many cases traditional celestial navigation and good old compass/map based land nav as well. I mean why not, you can buy a GPS system for sub-$100 these days.
From an article in Maritime Executive, MARAD found about ships operating in and around the Black Sea have observed cases of GPS spoofing. These included cases of lost signals and “For few days, GPS gave a position inland (near Gelendyhik aiport) but vessel was actually drifting more than 25 NM from it.”
This comes as the Navy has returned celestial navigation (CELNAV) courses to the Naval Academy’s curriculum (NROTC dropped it in 2000, USNA in 2006).
Further, an improved radio-nav system known as eLoran is making in-roads in navigational support with the Coast Guard being the proposed recipient of $200 million in funding to help muscle it up.
Police in Edmonton, Alberta, in conjunction with the Royal Canadian Mounted Police, found a pair of full-auto DIY MAC-11’s (out of an estimated six made) complete with matching suppressors as well as other sundry illegal arms last month.
Police say that a half-dozen MACs were made, but only two were recovered. (Photos: Edmonton Police)
Made in a machinist’s shop without his knowledge, “The MAC-11s were fully automatic, with one trigger pull resulting in the entire magazine of 30 rounds being fired in just seconds,” according to a release.
