Quite a unique moment, unexpectedly this formation appeared, old and new in formation near the Thomas-Jefferson memorial. Strikingly, the green colour of the Sea King is slight different compared of the colour of its successor, the Patriot. The VH-3D Sea King (BuNo 159359) is together with 159357 (which was seen earlier this day) is one of the last operational Sea Kings of HMX-1.

168280 from FY2011 is the first presidential Osprey (LRIP Lot 15). It flew first on 23 Jan'13 and was delivered to Marine Helicopter Squadron (HMX) ONE 'the Nighthawks' on 3 May'13. The Marine One Osprey's replaced a small number of CH-46 and CH-53s within HMX-1 and are used as support aircraft. They lack the white paint at the top of the fuselage (thus the nickname "white tops") that the VIP transport helicopters have. On 11 Aug'13 two MV-22Bs made their presidential debut ferrying Secret Service agents, White House staff, and members of the media from CGAS Cape Cod to Martha's Vineyard (MA).

Wow, this Black Hawk could be just a US Army one, but when going into detail, the word Army on the tail section is removed, the marking on the engine housing is not US Army, and the crew clearly show a Federal Bureau of Investigation (FBI) patch. And indeed, this UH-60M belongs to the FBI. The fiscal year of the serial is not 100% confirmed

The construction number of this Osprey is unconfirmed. The tilt-rotor is coming from the Lor Rate Initial Production Lot 115 series and was part of the US Navy FY2011 budget. As they are support aircraft, the are named "Green Tops", the other assetts of HMX-1 are named "White Tops" and these transport the VIPs. HMX-1 operates a dozen MV-22Bs.

The construction number of this Osprey is not known. The Marine Helicopter Squadron (HMX) ONE MV-22Bs are identical to those used by the USMC in the fleet, they only differ from their paint job.

This FY2019 Patriot carries a plate with a six on the "clip", I don't know what that means. Normally such clips are used for plates with two, three or four star marks. This 169187 is former Sikorsky test registration N335SX.
