| "Commissioning Pennant 
 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.
 
 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." Destroyer Escort Sailors Association
   ""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. 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 (national flag); 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)"" Source: Wikipedia |
