Ship project history: History of destroyers of this numerous family (272 ships were built), known as "flushdeckers", or "fourfunnells", begun in 1915, when leading particulars of the ships of the FY1916 program (DD69-74) were defined. The structure and armament arrangement have borrowed at previous class destroyers of Sampson class, but hull was designed the new. At the initiative of the Bureau of construction it has been fulfilled to flush-deck scheme, notably being dropped from a bow aftward (a depth in ship ends was the same, as on Sampson). Breadth of hull amidships have a little increased, while ship draught, on the contrary, was decreased. At the expense of new flush-deck architecture American designers tried to moderate susceptibility of new destroyers to pitching and roll (at the expense of some lightening of ship ends) and to raise a longitudinal strength. As because of decreased draught screws blades projected below a keel line, last has received a characteristic ledge in aft part. Project of new destroyer provided transition to triple-shaft machinery where HP cruising turbine worked on the central shaft. Similar decision allowed at bigger on 1000hp power to raise machinery efficiency. The sketch design provided a conclusion of smoke ducts from four boilers into three funnels (wide second funnel pooled two smoke ducts).
Destroyers of FY1916 program have built of six, but only two (DD72 and 73) were built under original design, designs of the remaining ones have brought a number of improvements, in particular, triple-shaft machinery with a direct drive have replaced by twin-shaft geared and each boiler received its own funnel (funnels again became four). An exception became DD71 with three funnels.
Trials of the first completed destroyers have appeared to some extent discouraging: both "prototypes", and followed them serial "flushdeckers" have appeared notably "wetter", in comparison with predecessors, and the pitching even has increased, at the expense of narrower contours of ship ends.
