(AK-16: dp. 11,450 (n.); 1. 401'0; b. 54'2; dr.
24'5"; s. 11.5 k.; cpl. 56; a. 2 5, 4 3)

Shannock-a cargo ship built in 1919 by American International Shipbuilding Corp. at Hog Island, Pa.— was acquired by the Navy from the United States Shipping Board on 16 November 1921 and renamed Spica (AK-16). Over the following 18 years, she remained out of commission-first at New York, then at Charleston, and finally at Philadelphia-from January 1927 until 1 March 1940, when Spica was commissioned at Norfolk, Va., Comdr. E. D. Gibb in command.

By mid-1940, Spica was assigned to the 13th Naval District; and, until late 1943, she sailed Alaskan waters carrying supplies to American outposts on the Alaskan coast and in the Aleutian Islands. During this

period, she participated in the campaign to reoccupy Attu. On 24 November 1943, she headed south to San Francisco, whence she departed again on 5 December. Heading via Funafuti, she reached Kwajalein Atoll in January 1944 and returned, via Pearl Harbor, to Seattle on 22 March. For the next six months, Spica resumed her Alaska-Aleutian circuit. In mid-September, she began a series of voyages from the west coast to Hawaii which continued until mid-March 1945. In all, she made four round-trip voyages between Seattle and Oahu. She returned to Seattle on 17 March 1945 and, on 7 April, once again took up the northern Pacific supply runs, completing her last at Seattle on 14 September. In October, she was declared surplus to the needs of the Navy; and, on 18 January 1946, she decommissioned at Seattle. Her name was struck from the Navy list on 7 February 1946, and she was delivered to the Maritime Commission for lay-up pending disposal. On 13 June 1947, her hulk was sold to J. T. Robinson, Ltd., a Canadian firm.

Spica was awarded one battle star during World War II.

Story of the Month December 2014

“I enlisted and I got on the wait list to join the Navy in early 1940. I had to be on the wait list because at that time they were not taking that many people. And also you had to have a recommendation from the chief of police, the parish priest and your high school principal attesting to your character before they let you in,” World War II Veteran Lieutenant Harry W. Patch, Jr. shared with the United States Navy Memorial film crew in Virginia during the summer of 2014.

Before enlisting in the Navy, Patch was interested in radio repair and electronics and had a radio operator’s license. His interest in radios would follow him throughout his service. Patch recalled, "I went to recruit training at New Port, Rhode Island…I got sent out to the Colorado and was in the deck force for about a week. They found out I had a radio operator’s license so they put me on the radio gang. It was a 40 man radio gang, and I was the junior man so I made coffee for everybody.” Patch would serve in the radio gang on the USS Colorado BB 45 and due to his radio operator’s license and prior knowledge of Morse code he could stand watches because he already knew how to operate the machinery. He remembered fondly one conversation he learned of concerning the Colorado’s upcoming role in the fall and winter of 1941. He remarked, “In September of ‘41 the Colorado went to Bremerton Naval Yard for an overhaul. And that’s a story by itself because we belonged to Battleship Division 4 and the flagship was USS West Virginia. It was the West Virginia’s turn to go into the Navy Yard and the Chief of Staff came over to check out the flag quarters and went back and a marine that came back told me he overheard the Chief of Staff telling the Admiral, ‘You won’t like the Colorado, it was never meant to be a flagship, the flag quarters are terrible.’ So the Admiral made the command decision, ‘Ok, send the Colorado back to the Navy Yard and we’ll stay here.’ As a result, the West Virginia was sunk. We were in the Bremerton Navy Yard and we escaped, we were the only battleship not sunk at Pearl Harbor.” Patch would soon be on his way to the Pacific War, but not aboard the USS Colorado. Patch would be sent to the USS Spica (AK-16) and assigned as a Direction Finder Operator.

He remarked about his memory of December 7 th , 1941, “I was on watch and copied the message, ‘Air raid at Pearl Harbor, this is no drill’, and the Captain said, ‘I don't believe it, I don't believe it’, and I said, ‘Captain believe it, they are saying it over and over, Air raid at Pearl Harbor, this is no drill.’” Patch would serve in the Pacific throughout the War and continued his service until 1962.

World War II activation and operations

By mid-1940, Spica was assigned to the 13th Naval District and, until late 1943, she sailed Alaskan waters carrying supplies to American outposts on the Alaskan coast and in the Aleutian Islands. During this period, she participated in the campaign to reoccupy Attu. On 24 November 1943, she headed south to San Francisco, California, whence she departed again on 5 December.

Heading via Funafuti, she reached Kwajalein Atoll in January 1944 and returned, via Pearl Harbor, to Seattle, Washington, on 22 March. For the next six months, Spica resumed her Alaska-Aleutian circuit. In mid-September, she began a series of voyages from the U.S. West Coast to Hawaii which continued until mid-March 1945. In all, she made four round-trip voyages between Seattle and Oahu. She returned to Seattle on 17 March 1945 and, on 7 April, once again took up the northern Pacific supply runs, completing her last at Seattle on 14 September.

A Tin Can Sailors
Destroyer History

The BANCROFT (DD-598) was launched on 31 December 1941 at Quincy, Massachusetts, and was commissioned on 30 April 1942. Off Casco Bay, Maine, in early June, she participated in ASW exercises with the LARDNER (DD-487), LANSDOWNE (DD-486), FITCH (DD-462), and BAILEY (DD-492). During June maneuvers, the BANCROFT, NICHOLSON (DD-442), WOOLSEY (DD-437), and MC CALLA (DD-488) hunted a submarine suspected of prowling off Mount Desert Island, responding to a sound contact with depth charges but never confirmed a hit.

By August, she and the MCCALLA were bound for the Pacific, arriving at Dutch Harbor, Alaska, in September 1942. She operated at various times with the CALDWELL (DD-605), which suffered a crushed bow in a collision with the SPICA (AK-16) as well as the CASE (DD-370), COUGHLIN (DD-606), and KING (DD-242). In October, the BANCROFT, BAILEY, and LONG (DMS-12), with the ST. LOUIS (CL-49) and NASHVILLE (CL-43), formed Task Group 8.7 to intercept and destroy enemy shipping. Later that month, with the INDIANAPOLIS (CA-35), the ships were designated Task Group 8.6 and ranged north of the Aleutians. In January 1943 they participated in the assault and occupation of Amchitka Island. Off Amchitka on 12 January 1943, the BANCROFT and CHANDLER (DMS-9) stood by as the DEWEY (DD-349) and MIDDLETON (APA-25) rescued the crew of the WORDEN (DD-352), which was aground and breaking up near the harbor entrance.

In May she covered the assault and capture of Attu Island and continued to patrol the approaches to Attu, Kiska, and Adak until 29 June, when she and the COUGHLIN returned to San Francisco for overhaul. Back in the Aleutians in August, she took part in the landings on Kiska Island during which the ABNER READ (DD-526) was seriously damaged by an underwater explosion. Taking the destroyer in tow, the BANCROFT searched for survivors. The next day, she took aboard two seriously wounded men from the beach who were cared for by her ship’s doctor.

Following her transfer to Pearl Harbor in September 1943, she began a steady routine of fire support, screening, and escort duties. Her first assignment was with Task Group 15.9 for carrier strikes against the island of Tarawa on 18 September. Next, with Task Group 14.2, she bombarded installations on Wake Island. By November she was escorting LSTs to Funa Futi, Ellice Islands, continuing on to Tarawa for the assault and capture of that atoll.

Between 31 January and 16 February 1944, the BANCROFT, HALLIGAN (DD-584), COUGHLIN, and CALDWELL, alternated screening duties during strikes against Kwajalein, with the HULL (DD-350), DEWEY (DD-349), HEERMAN (DD-532), MILLER (DD-535), HAILEY (DD-556), and MEADE (DD-602). While with carriers off Majuro in early March, she rescued a number of crews from downed planes. She, DEWEY, EDWARDS (DD-619), PHELPS (DD-360), MACDONOUGH (DD-351), HULL, and MEADE then moved on to cover the landings on Mille Atoll and strikes against the Palau Islands until 2 April 1944. The BANCROFT put to sea again bound for Hollandia and Wakde and operations on 21󈞄 April. Returning from the New Guinea area, her task group raided Truk, Satawan, and Ponape on 28󈞊 April.

In May DesRon 14, made up of the BANCROFT, MEADE, EDWARDS (DD-619), FRAZIER (DD-607), and CALDWELL, formed the Eastern Marshalls Patrol Group covering Mille, Jaluit, Maloelap, and Wotje. On 23 May, the BANCROFT and EDWARDS bombarded Wotje Island, silencing a shore battery. On 8 June, under heavy shore battery fire, the BANCROFT rescued a Corsair pilot off Mille. The ship suffered no material damage but one of her crew received a minor shrapnel wound.

By 25 June, the BANCROFT was off Saipan and on that night conducted harassing bombardment of the town of Tinian. She subsequently performed escort duties between Eniwetok and Saipan through the end of July. On 8 August she and the GANSEVOORT (DD-608) bombarded Maloelap Atoll. Ten days later, DesRon 14 left for Pearl Harbor and from there, the BANCROFT, EATON (DD-510), and PRINGLE (DD-477) returned to San Francisco for overhaul. She was back in the war early in 1945 and on 28 February was underway for Mindoro and then Zamboanga, Mindanao, to screen the forces occupying that island. Her next mission was to cover minesweeping operations in the San Bernardino Straits and then the landings at Legaspi in the Albay Gulf. On the night of 3 April, off Allen, Samar, the BANCROFT picked up the survivors of an army B-25 that had crashed on Catanduanes Island.

Spica AK-16 - History

The TC-50 is a deceptively simple two-way loudspeaker based on a 6-1/2 inch acoustically suspended woofer and a 1 inch dome type tweeter. Its crossover network is truly state-of-the-art, in parts quality, circuit layout and, of course, design. The compact speaker is the result of exhaustive research and the latest technology in computer assisted optimization. Designer John Bau had indeed pushed the limits with tools available for the period, creating a time-aligned design with remarkable imaging qualities. Close tolerances were maintained during production and units were serialized to ensure a optimal left/right matching.

The TC-50 was produduced in Walnut and Oak wood laminates, glossy black vinyl laminate and there was a single run of 10 in glossy piano black finish. John Bau stated "Opus One [Pennsylvania] (who sold more TC50's than anyone by far) wanted to offer a black finished cabinet. Their owner, Tasso Spanos, wanted a "real" piano black. We (i.e. Spica and the cabinet maker) weren't sure it could be done in a cost-effective manner, so we all agreed to do a run of ten. After finishing them, the cabinet maker said no way, he would have to charge a hefty premium for them. So after that we went for a vinyl black laminate, which I thought looked pretty good."

Analysis of Spica’s parallax shows that it is located at around 250 ± 10 light-years / 77 ± 4 parsecs away from the Sun. Both stars are several times bigger than our Sun. The primary Spica star has around 11.43 times the sun’s mass while the secondary Spica star has around 7.21 solar masses.

Both stars have greater radii than our sun, with the primary Spica star having around 7.47 solar radii thus a diameter of around fourteen times that of the sun. The secondary Spica star has around 3.74 solar radii, thus around seven times the sun’s diameter.

Don't Say You Weren't Warned

A victorious President Biden will move from his Delaware basement to the cellar of the White House, where he will remain only to be seen by the public in prerecorded, televised “Messages to the People.”

The riots will stop. After which, the suspiciously trained, organized, and supplied “grassroots Antifa rioters” will be “unofficially” incorporated into the Biden administration as “Local Policy Councils” financed by leftist dark money and tasked to root out disobedience and dissent. Thereby, Jerry Nadler’s Antifa “myth” will be in a position to enforce the much needed “hope and change” Biden has said he wishes to bring back.

Despite a distinct lack of promise in his future, Joseph Biden is a man who makes many promises. There was, however, one promise he made in the Democratic debates that is suspiciously absent from his recent professions of intent.

Biden (or whoever is pulling his strings) will have full control of the legislative branch of government -- either by the Democrats keeping the House, and winning the Senate in 2020, or through persuasion by Local Policy Councils of certain Republican senators, congressmen, and their families -- which of course, corporate media will ignore. The filibuster will be eliminated to grease the path of progressive legislation.

He will spend the first two years consolidating control of Congress. The census redistricting, as modified by the Local Policy Councils and intimidated state legislatures, will ensure Democrat control of both houses of Congress by a landslide in the 2022 midterms. Perhaps, even securing the two-thirds of both Houses necessary for the elimination of the electoral college.

Still, the only way to assure implementation of the left’s promise to “fundamentally transform The United States of America,” is to disarm Americans.

Starting slowly, Biden will precipitously increase taxes on guns and ammunition while restricting the amount of ammunition that can be legally purchased in a month. There will be mandatory gun registration under penalty of law. Failure to register will subject gun owners to felony prosecution, fines starting in the tens of thousands of dollars, and civil forfeiture of property such as real estate and cars.

Then, after the midterm elections, with the left in full control of the legislative and executive branches of government, laws will be passed outlawing all guns in private hands (an exception will be made for Local Policy Council members).

Gun confiscation will begin.

Any records the federal, state, and local governments possess pertaining to gun ownership will be made public with the release of the names and addresses of all gun owners nationwide. Employers will be encouraged to terminate any employees who are gun owners. Mortgage companies, banks, and credit card companies will be encouraged to decline financing to gun owners, “Local Policy Councils,” nee Antifa, will be encouraged to “peacefully protest” at the places of employment and homes of gun owners.

The Local Policy Councils, employers, banks, and financial firms will be indemnified against lawsuits pertaining to these actions. In addition, the Local Policy Council members as a quasi-militia will be protected by qualified immunity.

The same tactics used to such devastating effect in the rioting we have witnessed these last few months will now be used against doxed gun owners. Nightly visits by screaming, armed, and violent “mostly peaceful” council members will become prevalent. Arson, damage to private property, violent assaults, homicide, and even rape will become a “tool of the people” deployed to ensure recalcitrant gun owners “voluntarily” surrender their weapons. Again, corporate media will ignore these incidents.

Having deployed the National Guard and active-service troops from the Army throughout the 50 states, joint teams of disarmed and unfunded police, troops, Guard units, and Local Policy Council members will search homes for any unregistered guns.

Soros prosecutors and the success of the “decarceration movement” will allow socially distant incarceration of those who refuse the sensible new gun reform.

Well… that's the plan, anyway.

Apocryphally, Otto von Bismarck is said to have remarked, “God looks out for fools, drunkards, and the United States.”

The fools on the left are not going to know what hit them.

The left’s power is concentrated on the coasts and in large cities. The vast majority of this country, what is derisively called “flyover country” by those on the left, is relatively conservative and armed to the teeth. In most of America, people believe they can never be too thin, too rich, or too well-armed. It is estimated there are anywhere from 350 million to 700 million guns in private hands, and anecdotally, the higher number is probably still too low.

Remember COVID, the Chinese flu the CCP (Chinese Communist Party) deliberately infected the world with? Like all Chinese products it did not work as advertised but we locked down the economy anyway.

Well, one of the big reasons people did not starve is because truckers kept trucking. Most drivers keep a gun in their cab. When authorities confiscate that gun, deliveries to the cities will cease. It would be a matter of weeks before New York and LA started to run out of food.

How many homeowners do you think would need to be assaulted before a visit from the Local Policy Council would be met with gunfire? Council members are not trained for what they will provoke and can expect to be decimated in confrontations.

How long before people start to organize and directly attack authorities and lines of communication, in and around the cities? Keep in mind every hunter is something of a sniper. How long before some of them decide to lie in wait to pick off public officials responsible for these policies? America is also chock full of trained veterans. It does not take a brain surgeon to realize what side they will be on. Pipelines, power plants, interstate highways, railroads, and bridges will all be targets of attack.

Governors, mayors, and LEOs will start to defect, as will National Guard and any other troops who will resent being asked to kill their neighbors and relatives.

There are not enough soldiers, National Guard, and potential Local Policy Council members to protect everything or seize all weapons.

The fact is, Americans will never allow the government to take their guns, period!


Spica is believed to be the star that gave Hipparchus the data that led him to discover the precession of the equinoxes. [10] A temple to Menat (an early Hathor) at Thebes was oriented with reference to Spica when it was built in 3200 BC, and, over time, precession slowly but noticeably changed Spica's location relative to the temple. [11] Nicolaus Copernicus made many observations of Spica with his home-made triquetrum for his researches on precession. [12] [13]

As one of the nearest massive binary star systems to the Sun, Spica has been the subject of many observational studies. [14]

Analysis of its parallax shows that it is 250 ± 10 light years from Earth. [1]


Spica is located in the constellation Virgo. It marks the ear of grain held in the celestial Virgin’s left hand. Like other zodiac constellations, Virgo is one of the Greek constellations, first listed by Ptolemy in the 2nd century CE. It is the second largest constellation in the sky, after Hydra, occupying an area of 1,294 square degrees.

Virgo constellation, image: Roberto Mura

Virgo contains as many as 11 Messier objects (bright deep sky objects catalogued by the 18th century French astronomer and comet hunter Charles Messier), most of them part of the Virgo Cluster, the nearest large galaxy cluster to our galaxy. Its brightest members are visible in small telescopes. The centre of the cluster is found within the Spring Triangle, about halfway between Denebola in Leo and Vindemiatrix in Virgo. Member galaxies include Virgo A (Messier 87), a supergiant elliptical galaxy whose supermassive black hole was the first to be directly imaged, the bright elliptical galaxy Messier 49, the barred spiral galaxies Messier 58, Messier 61 and NGC 4639, and the interacting pairs NGC 4435 and NGC 4438, also known as the Eyes Galaxies, and NGC 4567 and NGC 4568, nicknamed the Butterfly Galaxies.

Virgo is also home to the famous Sombrero Galaxy (Messier 104), located 11.5 degrees west of Spica, and the supergiant elliptical galaxy IC 1101, one of the largest galaxies ever discovered.

The best time of year to observe the stars and deep sky objects of Virgo is during the month of May.

The 10 brightest stars in Virgo are Spica (Alpha Vir, mag. 0.97), Porrima (Gamma Vir, mag. 2.74), Vindemiatrix (Epsilon Vir, mag. 2.826), Heze (Zeta Vir, mag. 3.376), Minelauva (Delta Vir, mag. 3.39), Zavijava (Beta Vir, mag. 3.604), 109 Virginis (mag. 3.72), Mu Virginis (mag. 3.88), Zaniah (Eta Vir, mag. 3.89), and Nu Virginis (mag. 4.04).
