Flight of Boeing Super Hornet with IRST Block II Initiates FA-18 Block III Conversion

Boeing and the USNavy flew an F/A-18 Super Hornet equipped with an Infrared Search & Track (IRST) Block II pod completed its first flight in late 2019, the company announced on Wednesday.

IRST Block II is a critical component of the Block III Super Hornet. The Block III conversion will include enhanced network capability, longer range with conformal fuel tanks, an advanced cockpit system, signature improvements and an enhanced communication system. The updates are expected to keep the F/A-18 in active service for decades to come.

The Block III Super Hornet will have features comparable to fifth-generation fighter jets minus stealth and internal weapons bay. Boeing has no plans to develop an all-new fighter jet and the F/A-18 Block III Super Hornets will keep the jet contemporary in terms of weapons, communications and target seeking features.

IRST is a passive, long-range sensor incorporating infrared and other sensor technologies for highly accurate targeting, Boeing claims.

“The IRST Block II gives the F/A-18 improved optics and processing power, improving pilot situational awareness of the entire battle space,” said Jennifer Tebo, Boeing Director of F/A-18 Development.

Currently in the risk reduction phase of development, IRST Block II flights on the Super Hornet allow Boeing and the Navy to collect valuable data on the system before deployment to the fleet. The Block II variant will be delivered to the Navy in 2021, reaching Initial Operational Capability shortly thereafter.

“The IRST Block II sensor gives Navy fighters extended range and increasing survivability. This technology will help the Navy maintain its advantage over potential adversaries for many years,” said Kenen Nelson, Lockheed Martin Director of Fixed Wing Programs, supplier of the IRST sensor.
