Asked Questions page. The act of placing a ship in commission marks her entry into active Navy service. At the moment when the commissioning pennant is broken at the masthead, a ship becomes a Navy command in her own right, and takes her place alongside the other active ships of the Fleet.
This ceremony continues a tradition some three centuries old, observed by navies around the world, and by our own Navy since December 1775, when Alfred, the first ship of the Continental Navy, was commissioned at Philadelphia. Once in commission, the commanding officer and crew are entrusted with the privilege, and the responsibility, of maintaining their ship’s readiness in peace, and of conducting successful operations at sea in time of war.
No written procedure for commissioning was laid down in our Navy’s early days, but the act of commissioning was familiar, derived from established British naval custom. Commissionings were simple military ceremonies. The prospective commanding officer came on board, called the crew to quarters, and formally read the orders appointing him to command. He then ordered the ensign and the commissioning pennant hoisted; at that moment the ship went into commission, and the first entry in the ship’s deck log recorded this. First logs from a sizable number of early Navy ships did not survive and, since commissionings were not surrounded by any public fanfare, they were not written up in the press. We thus cannot know exactly when many of the Navy’s first ships were first commissioned; all that can sometimes be known is when a particular ship first put to sea.
The commissioning pennant is the distinguishing mark of a commissioned
Navy ship. A commissioning pennant is a long streamer in some
version of the national colors of the Navy that flies it. The
American pennant is blue at the hoist, bearing seven white stars;
the rest of the pennant consists of single longitudinal stripes
of red and white. The pennant is flown at all times as long as
a ship is in commissioned status, except when a flag officer or
civilian official is embarked and flies his personal flag in its
place.
Ships' commissioning programs often include a story about the
origin of the commissioning pennant. As it goes, during the first
of three 17th-century Anglo-Dutch naval wars (1652-54) the Dutch
Admiral Maarten Tromp put to sea with a broom at his masthead,
symbolizing his intention to sweep the English from the sea. His
British opponent, Admiral Robert Blake, two-blocked a coachwhip
to show his determination to whip the Dutch fleet. Blake won;
in commemoration of his victory a streamerlike pennant, called
a "coachwhip pennant" from its long, narrow form, became
the distinguishing mark of naval ships.
This is an interesting anecdote. As with so many other stories,
though, nothing has ever been found to prove it. Researchers in
England have tried to verify the tale, but without success. The
actual origin of the commissioning pennant appears to be a bit
more prosaic.
Narrow pennants of this kind go back several thousand years. They
appear in ancient Egyptian art, and were flown from ships' mastheads
and yardarms from, at least, the Middle Ages; they appear in medieval
manuscript illustrations and Renaissance paintings. Professional
national navies began to take form late in the 17th Century. All
ships at that time were sailing ships, and it was often difficult
to tell a naval ship from a merchantman at any distance. Navies
began to adopt long, narrow pennants, to be flown by their ships
at the mainmast head to distinguish themselves from merchant ships.
This became standard naval practice.
Earlier American commissioning pennants bore 13 white stars in
their blue hoist. A smaller 7-star pennant was later introduced
for use in the bows of captains' gigs, and was flown by the first
small submarines and destroyers. This principle even carried over
into the national ensign; bigger ships flew the conventional flag
of their time, while small boats used a 13-star "boat flag"
which was also flown by early submarines and destroyers since
the standard Navy ensigns of that day were too big for them. The
13 stars in boat flags and in earlier pennants doubtless commemorated
the original 13 states of the Union. The reason behind the use
of 7 stars is less obvious, and was not recorded, though the number
7 has positive connotations in Jewish and Christian symbology.
On the other hand, it may simply have been an aesthetic choice
on the part of those who specified the smaller number.
Until the early years of this century flags and pennants were
quite large, as is seen in period pictures of naval ships. By
1870, for example, the largest Navy pennant had an 0.52-foot hoist
(the maximum width) and a 70-foot length, called the fly; the
biggest ensign at that time measured 19 by 36 feet.
As warships took on distinctive forms and could no longer be easily
mistaken for merchantmen, flags and pennants continued to be flown,
but began to shrink to a fraction of their earlier size. This
process was accelerated by the proliferation of electronic antennas
through the 20th Century. The biggest commissioning pennant now
has a 2.5-inch hoist and a 6-foot fly, while the largest shipboard
ensign for daily service use is 5 feet by 9 feet 6 inches (larger
"holiday ensigns" are flown on special occasions).
