S-2 Tracker aircraft, produced by Grumman, served the United States Navy with honor conducting anti submarine warfare from 1954 through 1976. Now it serves with the California Dept. of Forestry in its new role.
The S-2 Tracker began being evaluated by the California Dept. of Forestry 1970 for duty as an air tanker. At the time it was still deployed with the U.S. Navy.
A total of four aircraft were evaluated by the CDF. They were found to meet or exceed all expectations. Two of the prototype air tankers were placed in service in 1973.
The CDF entered into contracts with four California companies in 1974 to convert 12 more S-2 Tracker aircraft into air tankers. These aircraft entered service in that same year, with an additional five aircraft entering service in 1975.
Through the years the CDF has purchased 55 S-2 Trackers and 60 replacement engines from the Navy under three agreements.
In 1987 the CDF contracted with Marsh Aviation, Mesa, AZ to produce a Tracker air tanker for evaluation. By 1996, after a thorough evaluation, the CDF ordered an additional 26 E and G series aircraft. The E and G series aircraft are larger and carry 400 gals. more retardant than the older S-2s.
Throughout 2002 a total of 13 S-2 Tracker aircraft were deployed. In 2004 and 2005 a total of ten additional aircraft were added to the fleet. These have replaced the original air tankers.
Pictured above is the rc S-2 Tracker by master builder Carl Bachhuber. It has a wingspan of 165". Carl powers his rc airplane with a pair of G-62 engines. It features retractable landing gear, scale operational flaps, slotted spoilers, plus a working tail skid.
In the picture right below you will see Carl's rc S-2 Tracker with its wings folded. Carl removed the feature when he found the operating mechanism needed a great dale of maintenance. A benefit of the removal is that his rc airplane now weighs about 62 oz. less.
