J.60 Spurvhauk

The J.60 Spurvhauk (Anglic: Sparrowhawk) is a retired Ringeriker, single-engine, lightweight fighter introduced in 1958. It was designed to replace the J.49 Tønne, Ringerike's first jet fighter. It was supplemented by Nieuport-Saulnier Mystère Fighters from 1965 and replaced by the J.71 Torden, however it survived as a trainer until 1990. The type was also famously used by the 504th Display Squadron (The Red Knights).

Prototypes

 * Hansen 54: Concept demonstrator first flown in 1954, smaller in scale even than the J.60, it was developed as a private venture in anticipation of the requirement for a lightweight replacement for the J.49. It was rejected for further development for being too small however its flight characteristics were widely praised and the Luftforsvaret accepted a proposal for a larger, more capable version to be developed.


 * Hansen Eks.55: The product of the above mentioned development, designed to be a lightweight, nimble fighter with a limited ground attack capability, it was accepted into trials after its first flight in 1955, performing admirably.

Production Models

 * J.58 Spurvhauk: Single seat subsonic lightweight fighter powered by a RAEC Mk.18 turbojet introduced into service in 1958, most airframes were shortly scrapped or repurposed into trainers as the J.60 came into production.


 * J.60 Spurvhauk: Single seat supersonic lightweight fighter powered by a Reheating RAEC Mk.18B turbojet introduced into service in 1960, other changes included an altered wing, and the adding of an air intercept radar.


 * R.60 Spurvhauk: Photo-Reconnaissance variant of the J.60 fitted with with three nose-mounted 70mm cameras, retained combat capabilities.


 * T.61 Spurv: (Anglic: Sparrow) Two seat advanced trainer aircraft for the Luftforsvaret, and longest serving of the variants, not being formally retired until the 1980s. Powered by the RAEC Mk.18 of the J.58 as supersonic capabilities were seen as not necessary and potentially hazardous when paired with new pilots.


 * T.64 Havspurv: (Anglic: Sea Sparrow)Two seat carrier trainer aircraft for the Kongelig Marine. Featuring a strengthened landing gear and arrestor hook as well as a series of other adaptations. It was proposed to develop the T.64 into a lightweight carrier fighter however this option was not pursued.
