CONVAIR F-106 Delta Dart

History

The F-106 "Delta Dart" originated from an initial request by the US Air Force to produce the high-performance F-102 "Delta Dagger" in 1956. The F-102 was developed by the U.S. Air Force program in the early 1950s to deploy a powerful interceptor against the threat of long-range, high-flying Soviet nuclear-tipped bombers. The F-102 used an advanced delta wing configuration with special area rule specifications derived from German war trials on the subject. The Delta Dagger first flew in October 1953 and was officially deployed in April 1956 to accommodate dozens of American interceptor squadrons in Europe and the Pacific.

Of these, 1,000 were produced, including a two-seater trainer, with Turkey and Greece as its only export customers. All versions are equipped with air-to-air missiles and optional missiles via three internal weapons bays, and feature a Hughes-designed Fire Control System (FCS).

However, the F-102 was only a "preliminary" interceptor package for the proposed engine, and the development of the FCS was delayed. As such, the series was used with the less powerful Wright J57 turbojet, which could only fly at Mach 1. It can be seen that the initial F-102A production model will help "bridging" the gap with the upcoming final F-102 form, leading to the "F-102B" production brand with the real engine and weapons package it should be. Sections of the F-102B were lengthened with the introduction of the Pratt & Whitney J-75-P-17 turbojet, with larger air intakes and variable-geometry air ducts within the lengthened fuselage (high-speed and high-altitude flight). required) fuselage assembly.

The wings and vertical stabilizers have been redesigned to increase the surface area while improving stability. An idle thrust retarder was added to the engine exhaust ring at the rear of the fuselage.

Due to numerous major changes, the aircraft was ordered by the USAF as a pair of "YF-106A" prototypes. The first flight took place on December 26, 1956, and the U.S. Air Force envisioned 1,000 of these aircraft in its inventory.

In practice, the F-106 performed admirably, and its pilots had a great time in the cockpit - a "hot rod" in its purest form. The highly technical aircraft was not without flaws, however, as its advanced MA-1 fire control system proved cumbersome throughout its career, despite numerous attempts to fix software and functionality. Their ejection seats also proved deadly to their early pilots, killing all 12 in their respective attempts. Additionally, F-106s were produced in extremely limited numbers compared to the 1,000 F-102s delivered, and they were only in service with the Air Force's Air Defense Command before being delivered to the Air National Guard.

No one ever fought while stationed at bases in Europe, Iceland, Alaska, and South Korea (except the F-102, which served for a while in the Vietnam War). At its peak, the F-106 had 13 U.S. interceptor squadrons, while the F-102 had 26.

Attempts to improve the aircraft through various upgrade programs. However, the success of the remarkable McDonnell Douglas F-4 Phantom II quickly ended all future hopes for the F-106 series, as it proved to be the better platform in almost every conceivable category. War experience in Vietnam also revealed several requirements that the F-106 lacked - including excellent cockpit visibility, extended gun carrying capacity and - of course - an internal cannon (F-4E).

The "rocket warfare" planned by American war planners never materialized, as hand-to-hand combat proved effective.

A new initiative was proposed in 1972 to help make several major modifications to the F-106 family. This included the installation of a 20mm internal Gatling cannon, as well as a "bubble" canopy (this replaced the original frame version). Even so, time and technology are not on the F-106's side. Over time, the plane was inevitably left out of the Air Force's long-term plans. The arrival of the McDonnell Douglas F-15A Eagle "air superiority" fighter marked the end of America's last dedicated interceptor.

The F-106 represented the dominant aircraft type on the ADF roster at the time and remained in service until 1981, after which the systems were transferred to the Air National Guard to complete their useful life. Others were converted into aerial target drones for USAF training.

The ANG example remained in service until 1988, and the F-106 in UAV form until 1998.

Including two development prototypes and a two-seat trainer, F-106 production peaked at 342. Production ended in 1962.
