Lockheed S-3C Viking
With the aging of the Grumman S-2 Tracker and the increasing effectiveness of Soviet submarines, the US Navy issued a requirement for a new carrier-based ASW aircraft. Lockheed won the contract, partnering with LTV to design carrier-specific equipment and Univac to design the ASW suite. The resulting S-3A Viking first flew in January 1972 and entered the fleet in February 1974.
While the S-2 integrated the hunter-killer team concept into a single airframe, the S-3 went one step further by completely computerizing the sub-hunting process, integrating the entire sensor suite into one system rather than in several as on the S-2. Initially, this employed a Univac AN/AYK-10 computer served by Texas Instruments AN/APS-116 radar and AN/ASQ-81 MAD sensor in a retractable tail boom. Flown by a crew of four, the S-3’s interior was so efficient that one aviation writer described it as the most compactly designed aircraft in history.
The S-3A--nicknamed "Hoover" for the sound of its engines-- acquired a reputation for being a reliable, easy to fly aircraft, and spawned a number of variants, including the US-3A carrier-onboard delivery (COD) transport aircraft and the ES-3A Shadow Elint variant. A dedicated KS-3A tanker never went into production, but S-3s were increasingly equipped with buddy refuelling packs. When the KA-6D Intruder dedicated tanker was retired from the US Navy in the mid-1990s, the S-3 took over the role, though its relatively slow speed meant it could not accompany strikes into enemy territory. Despite that, the S-3 always had the capability to carry not only antisubmarine ordnance such as torpedoes and depth charges, but also bombs and later the AGM-84 Harpoon antiship missile and AGM-65 Maverick AGM. The S-3’s antiship capability was used in both Gulf Wars: in 1991, a S-3 sank an Iraqi attack boat with conventional bombs, while in 2003 a S-3 destroyed an Iraqi command post with a Maverick in Basra.
Beginning in 1991, the S-3As in service were modified to S-3B standard, with upgraded avionics and a new APS-127V synthetic-aperature radar, giving the S-3B a significant ship-detection and SAR capability as well. Though the ES-3A was withdrawn from service in the mid-1990s, several S-3Bs were converted to littorial reconnaissance (Gray Wolf) and ground surveillance (Brown Boy) roles. With the reduction of submarine threats to the US Navy, the S-3 fleet is being gradually retired; those remaining in service have had their ASW equipment removed and serve primarily as tankers. Their role has been largely replaced by the SH-60B/F Seahawk series, and, aside from a handful of test aircraft, the S-3 was retired in 2009.
If you're like me and you like small-scale aircraft, like to do what-ifs, and are on a budget, the Micro Machine toy collection might be worth getting into. A few years ago, I picked up a Micro Machine P-3 Orion and this S-3 Viking at a used toy store in Phoenix, and finally got around to the S-3 a few months ago. It originally came in "Bad Guy" camouflage (which looked a lot like the US Navy RA-3 scheme in Vietnam), but I went with the overall, albeit boring, light gray used by the Navy towards the end of the S-3's career. This one, however, belongs to my fictional Free Intelani Naval Air Arm.
Because of its tiny size, there isn't a lot of room for markings on something this small, so tailcodes and such are beyond my ability. All the same, the marking on the tail is supposed to be a stylized kangaroo (as the S-3 did a lot of up-and-down while hunting submarines), marking this as an aircraft of Naval Air Antisubmarine Squadron 1.
For their size, the Micro Machine line has a good bit of detail and panel line work, so this ended up turning out pretty well, all things considered.
