THE SUPERMARINE "SWAN" COMMERCIAL FLYING BOAT
Further Flight Trials at Southampton

  ON June 9, some further flying trials were carried out at Southampton with the large twin-engined amphibian flying boat designed some time back by the Supermarine Aviation Works, Ltd., of Southampton. The Supermarine "Swan," the flying boat in question, was actually constructed in 1924 to the order of the Air Ministry for passenger work, and was launched on March 25, 1924, but was not at that time equipped for passenger carrying, and was fitted with two Rolls-Royce "Eagle IX's ".
  Shortly after the "Swan" went to Felixstowe for its official trials, which proved so satisfactory that the Air Ministry decided that, with certain modifications, it would make an efficient Service machine. Mr. Mitchell, its designer, therefore, set to work in re-designing the "Swan" to suit Service requirements' and eventually evolved the "Southampton," which is now one of the standard machines of the R.A.F.
  In the meantime, the "Swan" went back to Southampton, and in due course was fitted out for the work for which it was originally intended - passenger-carrying for civil air lines. This work has recently been completed and, as previously stated, practical flying tests carried out.
  In its present form the "Swan" is fitted with two Napier "Lion" engines, whilst the cabin equipment, &c, presents several noteworthy features. The passengers' cabin is located in the hull, and is exceptionally roomy and conveniently laid out. Accommodation is provided for ten passengers, who are seated in comfortable wicker arm-chairs. These are arranged on either side of the cabin, leaving a small gangway in between. Beside each seat is a porthole in the wall of the cabin, through which the passenger has an excellent view of the sea-scape below.
  Forward of the cabin is a compartment for luggage, &c, access to which is by means of a door leading directly into the cabin and via a hatchway from the deck. Aft of the cabin there is lavatory accommodation.
  The interior of the cabin generally is bright and pleasing, the upper arched portion being given a light finish and is adorned with framed aviation pictures, while the lower portion has padded upholstery.
  Pilot and navigator are accommodated in a separate cockpit or "cabin" located on the top of the hull, between the main planes. All the controls are located at this point. The engines are mounted, as usual, on either side of the control cabin midway between the top and bottom planes, and each drives a four-bladed tractor air screw.
  On the occasion of its recent flying test the "Swan" carried its full complement of passengers, made up of eight young ladies employed at the Supermarine Works, a representative of Imperial Airways, and a member of the Press, whilst the pilot, Capt. H. C. Biard, was accompanied by Capt. F. J. Bailey, manager of the Woolston airport. After taxying to a favourable position opposite the Government Rolling Mills, the "Swan" took off in a comparatively short run and headed down Southampton Water to Hamble River, then turned back towards the docks. Flying at altitudes varying from 100 to 1,200 ft., the "Swan" made two trips to Lee-on-Solent, during which two perfect landings were made. After about an hour's flying, the "Swan" returned to its nest, having given a very satisfactory account of itself.
  It may be of interest to note in conclusion that news has just been received by the Supermarine Aviation Works, Ltd., from their chief designer, Mr. Mitchell, who is in Copenhagen, that a contract has been signed with the Danish Government for a large three-engined flying boat. This machine will be built at the Supermarine Company's Southampton Works, and will be fitted with three "Jaguar" air-cooled engines manufactured by Messrs. Armstrong, Siddeley, Ltd. It is worthy of note that this contract has been secured in the face of strong continental competition.

Originally serialled N175, the Swan G-EBJY was the aircraft from which the Southampton directly evolved.
SUPERMARINE SWAN. Designed by R. J. Mitchell - of the Spitfire - the Swan was the first twin-engined Supermarine flying-boat built. The name was actually first applied to a projected amphibian development of the first British transport flying-boat, the Sea Eagle. This earlier Swan was to have been a smaller machine with a single pusher 450-h .p. Napier Lion engine and accommodation for five passengers and a crew of two. It was not built.
The Swan with which we are concerned here was originally ordered by the Air Ministry (to Specification 21/22) as a twelve-passenger transport amphibian powered by two 360-h .p. Rolls-Royce Eagle IX engines. However, two Swan prototypes (N 174 and N 175) were completed in 1924 as military flying-boats without the amphibian undercarriage . These aircraft were equal-span, two-bay biplanes with monoplane tail units and triple fins and rudders . A feature of their design was a raised "deckhouse" above the lower centre-section containing a side-by-side cockpit for the crew of two.
One of the Swan prototypes was tested at the Marine Aircraft Experimental Establishment at Felixstowe in 1924 and showed such promise that an Air Ministry Specification (R.18/24) was issued soon afterwards for a development, later built by Supermarine as the first of the famous Southamptons.

The Supermarine "Swan" twin-engined amphibian flying boat is probably the first machine of its type in the world. The engines are Rolls-Royce "Eagle IX"
A NEW SUPERMARINE AMPHIBIAN FLYING BOAT: This machine, fitted with two Rolls-Royce "Eagle" engines, has been built for the Air Ministry, and it is not permissible to give technical details. The main features of the design will, however, be evident from the illustrations. Capt. Biard took the machine out recently, and, after a short taxying test which proved the machine to be satisfactory, he took off and carried out a flying test of 45 minutes' duration. An unusual feature of the design is the raised, or "coach-roof" cabin top. The high flaring bows should render the boat capable of riding out quite a heavy sea.
