S-3B Airtanker Design Summary

• US Government presented with a 250+ page design document describing performance, IATB compliance, and fleet cost analysis

• Over 45 Navy publications and 120 OEM drawings analyzed

• Most extensive S-3B airtanker engineering completed to date

• Sponsored by Air Force Research Labs, NASA: All data available at zero cost to USFS

Suitability• Takeoff & Landing performance is suitable for most USFS

firebases

– Engine modifications & thrust reversers are not required – Upgrade to latest TF-34 engine variants would increase speed, payload, fuel

efficiency

• Engines & Airframe are proven in the fire aviation environment

– Tens of thousands of flight hours in blowing sand, smoke, high temp.– Operating from forward-deployed desert airfields in hot climates

• Analysis & US Navy Flight Test Data Predict Full IATB Compliance

– S-3B airtanker will have lower drag count than existing US Navy flight test data

Supportability

• Maintenance

– Most recent S-3B Iraq deployment• 4 forward-deployed aircraft• 3 flights a day, 6 months• 100% mission completion; no

sorties lost to maintenance aborts• Continues the trend of 27%+ cost

savings vs. the P-3 airframe• Lowest cost carrier-based aircraft

– Over 80% average mission availability in Afghanistan, Iraq wars

– TF-34 engines shared by USAF A-10s, commercial RJs

– Over $1.2B in Navy spare parts, airframes, equipment – zero cost to USFS

– AMARC re-activation costs for S-3B are 50% those of P-3A/C

Structural Service Life

• Full Scale Fatigue Test (FSFT) analysis completed in 2004 by OEM and Navy engineering teams

• Tested two full scale models to failure against a tactical aircraft flight profile:

– Did not use transport aircraft load spectra (e.g. P-3, C-130, B747, DC-10)

– Tactical, low-altitude profile used instead

• Results– Exceeded previous life estimates by 100%– 23,000 hr. service life certification; average

airframe age is 12,000 hrs.– No re-winging required, 15-20 yrs. airtanker

life remaining– “It would be conservative to use these hours

to determine inspections or life limits on individual aircraft” – OEM FSFT Failure Analysis Report

Slide 13

Safety Record

• 1.7 million flight hours, 21 years operational service– S-3B’s Class A mishap rate is lower than the P-3C’s in USN

service

– 1 Class A involving engine failure – caused by human factors

– 1 Class A involving vertical fin failure – caused by human factors

– 2 Class A due to inflight fire – caused by maintenance malpractice

– 3 Class A due to analog autopilot system malfunction

– 4 Class A due to CV environment

– 19 Class A due to CFIT or other human factors

S-3B Class A Mishap Causal Factors

All Years
