When displayed with foreign ensigns, the U.S. ensign must be displayed to the extreme right and on the same  level.  International  usage  forbids  displaying  the  flag of one nation over that of another nation in time of peace. The national ensign of other nations is displayed to the left of  the  U.S.  ensign,  beginning  in  alphabetical  order.  The only exception to this rule is when the U.S. naval activity is in a foreign country, in which case that country's flag will be to the immediate left of the U.S. ensign without regard to alphabetical listing. In a semicircular grouping, all flags other than the U.S. ensign are displayed in alphabetical order starting from left and reading clockwise. The U.S. ensign is displayed in the middle of the semicircle. The  display  of  the  national  ensign  from  various flagpoles is contained in NTP 13; as a general rule, the right side of a flagpole is determined by looking from the main entrance of a building towards the pole. Flagpoles at naval shore activities are topped with a brass ball of appropriate size. Flag Size for Shore The   following   dimensions   may   be   used   in determining the size of the ensign to be flown. A larger size is flown on Sundays and holidays and a smaller size flown daily if such a choice is available. Height of flagpole Recommended size Less than 35 feet #8 (3' 6" × 6' 7 3/4") 35 to 55 feet# 7 (5' × 9' 6") Greater than 55 feet #5 (8' 11 3/8" × 17') Miscellaneous  Information The  union  jack  is  not  displayed  ashore.  The  church or Jewish pennant is not displayed above the national ensign ashore, but separately if desired. The following sites have been authorized to fly the national ensign 24 hours a day: U.S.  Capitol,  Washington,  D.C. White  House,  Washington,  D.C. Fort  McHenry,  Baltimore,  Maryland Home   of   Betsy   Ross,   Philadelphia, Pennsylvania U.S.   Marine   Corps   Iwo   Jima   Memorial, Arlington,  Virginia Battle  Green,  Lexington,  Massachusetts Washington Monument, Washington, D.C. Customs Ports of Entry HOISTING AND LOWERING The national ensign is never broken, but always hoisted briskly and smartly and lowered ceremoniously. The only exception to this practice is when the national ensign is hauled down briskly and smartly from the gaff as a ship shifts colors to the flagstaff when anchoring or mooring between the hours of 0800 and sunset. On board ships and crafts of the Navy, the union jack at the jackstaff is hoisted, lowered, and half-masted with the national ensign at the flagstaff. HALF-MASTING THE ENSIGN When half-masting the national ensign, it must, if not already hoisted, first be hoisted to the peak, then lowered to the half-mast position. Before lowering from half-mast, the flag must be hoisted to the peak and then lowered. When the President directs that the national ensign be flown at half-mast at military installations and aboard ships, it must be flown at half-mast whether or not the ensign of another nation is flown close-up alongside the U.S. ensign. When the national ensign is flown half-mast in ships or crafts of the Navy, the church or Jewish worship pennant, if flown, is hoisted just above the national ensign. If holiday colors are to be displayed on days other than Sundays and holidays, or if colors are to be displayed at half-mast on days other than Memorial Day, the senior officer present, at 0745, hoists the appropriate signal. If such signal is hoisted after 0800, colors must be shifted or half-masted when the signal is hauled down. If half-masting is ordered during periods of dress or full-dress ship, only the national ensign at the flagstaff is half-masted. NOTE On board ship or at a shore command, upon all occasions of hoisting, lowering, or half-masting of the national ensign, the mo- tion of the senior officer present must be followed  except  as  prescribed  for  answering a dip or firing a gun salute. Table 10-2 shows the occasions when the flag is half-masted as a symbol of mourning. As you can see by table 10-2, there are occasions when ships under 10-3
