FACTBOX: Sizing up Boeing's plane portfolio

(Reuters) - Boeing Co has halted commercial aircraft production after 27,000 machinists walked out on strike on Saturday.

The stoppage affects all Boeing's jetliner production from the 737 -- the world's biggest-selling aircraft and workhorse of many short- and medium-haul fleets -- to the classic 40-year-old 747, which is still made as a freighter. The newest version of the jumbo, the 747-8, has only just started production.

Also idle are the 767, the first transatlantic twin-jet, and the more recent 777 mini-jumbo. The strike will also halt progress on the 787 Dreamliner, a futuristic mid-sized jet made of carbon fiber.

Boeing's backlog of 3,696 jets is worth more than $400 billion at current list prices and represents some 6 years of production.

Here is a breakdown of the main Boeing models in production or development. NARROW-BODY (Single-Aisle) --------------------------
